Custom Styles are gone in Editor after upgrade

Hello

Problem is that after the update to Dropeditor version : 1.1.11
I can´t see the Custom Styles I created in the editor any longer
I can see them in the config area and they are stored in /plugins/editors/dropeditor/customstyles.css

This is what I get when I press the support button

Using
Joomla version : 3.6.5
Dropeditor version : 1.1.11
Php version : 5.6.15~phpboil.01

what is going wrong?

Regards
MiBa
