Why I have two same permissions

Question

I added permissions to database users by a T-SQL stored procedure like this:

GRANT SELECT ON [dbo].[tbl_BookSubCats] TO [LibraryMemberUser]

But now I have two permissions as the same, in ssms. See this screenshot:

And my Windows application doesn't indicate the permission and gets permission error.

Why this is happened and how can I solve this problem?

Thanks

You can check this forum and follow the steps:

right click on table and go to properties -> permissions tab -> click Add -> browse the user to whom u want to give the permission -> click ok -> now u will find various permissions which u can grant -> in tht tick on select checkbox under grant column.
