Android - Duplicated Icons after Build with Cordova

Question

Before I came here and ask I did a lot of research to figure out what happened that cause this problem but I didn´t found any answers that would help me.

Problem summary: we have a legacy app at work and I used cordova to build the app and emulate it on android studio. To build the app was everything ok, but I don´t know what happened that the icons was duplicated and the css deconfigured.

This is the configuration:

  Installed platforms:
   android 6.4.0
  Available platforms:
   browser ~5.0.1
   ios ~4.5.4
   osx ~4.0.1
   windows ~6.0.0
  Cordova:
   8.1.2 (cordova-lib@8.1.1)

This is what is looking like now:

Does anyone have any idea to help me figure out what caused this? I really apprecciate any help. Thank you.
