Version 5.1.0a (Build 4837)

I had some unwanted drop down lists that I deleted in the en_us.lang.php file. This worked fine.
I also edited some of the lists. This also worked fine.

My problem is that I can't seem to create new drop downs or add new items to an existing drop down list when using the Drop Down Editor.

I went to Repair - Clear Data Template Cache but this doesn't seem to change anything.

I gleaned most of the things I did from this forum but I haven't found a solution.

Thanks for any suggestions
