Wimgbax on "[Plugin: WP UI - Tabs, Accordions, Sliders] Cannot make tabs anymore"

With the minimum set up I continued my investigation.
I always used the drop down menu from the editor,because there you get the option to select content .
I went back to basic entered short code manually and then content.
The wrap tabs I did with the drop down menu after this very user unfriendly way it worked.
For me it looks like a problem in the back-end .
