The options selector for Sections, Containers, and Blocks grows to about ~390 px tall. This can overlap other elements preventing it from being selected. It seems not to have a height assigned so maybe a max-height would be suitable here?
Hi Sebastian,
Thank you very much for your report!
This looks very much like a custom CSS or plugin conflict. Please check your custom CSS first - you will probably find the problem. Look out for .option or .selected.
If that doesn’t work: deactivate one plugin after the other and check if the problem still exists.
