Help with Portal Theme design

Hello,

we recently upgraded our BI System from 7.30 SP 8 to 7.30 SP10.

After the Upgrade we encounter, that we have two frames within our Input Ready fields of our WAD iViews. I already tried to fix our custom theme, but I can not find the aprobiate part within the Theme Editor.

Does anyone of you know how to get ride of the inner frame of the fields and can tell me the place to edit in the Theme Editor?

I do not want to delete the theme and start from scratch again to rebuild our design.

Thanks in advance and BR

Stephan
