TYPO3 6.2: Tab “Appearance” disappeared (maybe caused by t3sbootstrap extension?)

Question

When editing an image content element in TYPO3, usually there is a tab "appearance" with options for image size, alignment, position etc. In my installation that tab is not showing, but instead a "nameless" tab. I'm using the t3sbootstrap extension and this behaviour might be caused by bootstrap.

Does anyone know how I can make the appearance tab visible and usable again? I've searched the internet but didn't find anything helpful so far. Thanks for your help!

Here is a screenshot from my backend:

Apparently this problem is caused by a corrupted TCA. I made the following changes in default TCA using System -> Configuration:

To restore the options for Layout, Top and bottom margins and frames , I set the following:

$TCA['tt_content']['palettes']['frames']['showitem'] = 'layout;LLL:EXT:cms/locallang_ttc.xlf:layout_formlabel, spaceBefore;LLL:EXT:cms/locallang_ttc.xlf:spaceBefore_formlabel, spaceAfter;LLL:EXT:cms/locallang_ttc.xlf:spaceAfter_formlabel, section_frame;LLL:EXT:cms/locallang_ttc.xlf:section_frame_formlabel';

To restore the appearance tab title:

In $TCA['tt_content']['types']['image']['showitem'] I changed LLL:EXT:frontend/Resources/Private/Language/locallang_ttc.xlf:tabs.appearance to LLL:EXT:cms/locallang_ttc.xlf:tabs.appearance

To restore the image adjustments:

In $TCA['tt_content']['types']['image']['showitem'] I changed --div-- to --palette-- right after the frames part and I added LLL:EXT:cms/locallang_ttc.xlf:palette.image_settings;image_settings, --palette--;LLL:EXT:cms/locallang_ttc.xlf:palette.imageblock;imageblock, --div--; after the frames part.

This is the result:

$TCA['tt_content']['types']['image']['showitem'] = '--palette--;LLL:EXT:cms/locallang_ttc.xlf:palette.general;general,                --palette--;LLL:EXT:cms/locallang_ttc.xlf:palette.header;header,        --div--;LLL:EXT:cms/locallang_ttc.xlf:tabs.images,                image,                --palette--;LLL:EXT:cms/locallang_ttc.xlf:palette.imagelinks;imagelinks,      --div--;LLL:EXT:cms/locallang_ttc.xlf:tabs.appearance,              --palette--;LLL:EXT:frontend/Resources/Private/Language/locallang_ttc.xlf:palette.frames;frames,        --palette--;LLL:EXT:cms/locallang_ttc.xlf:palette.image_settings;image_settings,                    --palette--;LLL:EXT:cms/locallang_ttc.xlf:palette.imageblock;imageblock,                --div--;LLL:EXT:cms/locallang_ttc.xlf:tabs.access,                --palette--;LLL:EXT:cms/locallang_ttc.xlf:palette.visibility;visibility,                --palette--;LLL:EXT:cms/locallang_ttc.xlf:palette.access;access,        --div--;LLL:EXT:cms/locallang_ttc.xlf:tabs.extended, , --div--;LLL:EXT:flux/Resources/Private/Language/locallang.xlf:tt_content.tabs.relation, tx_flux_parent, tx_flux_column, tx_flux_children;LLL:EXT:flux/Resources/Private/Language/locallang.xlf:tt_content.tx_flux_children';

Result

After making these changes, the result is the following:
