TinyMCE Error HELP Please

Hello everybody.

I have an unbelievable error in Admin>Builders>PageComposer>HTML Block Create/Edit

In TinyMCE all 4 DropDown fields => FontSize, FontFace, FontColor, BackColor

I would say - "flying" - in background - between Site and HTML Block window.

That I can not any property that I wish to choose.

I can not find a solution. I checked already all Tiny scripts. I changed already all old and new Tiny version... Nothing helps.

Had anyone any idea?

Thanks in Advance.
