Left side empty in admin of module

I upgraded our website to Joomla 3.2.0. When I go in the back-end of Joomla and go to your component in the Module tab the left side of this tab is empty. I do not see anything to select. I tested this in IE11 and Chrome 30.

First you have to tell me which "your component". If you mean AJAX Register attached is the screenshot of it running in Joomla 3.2, also upgraded from 3.1. As you can see it's running just fine, nothing missing.

So maybe your upgrade was bad, check if you get same problem with other components, try with clean Joomla 3.2 installation too and make sure you have very latest version of "my component".

Sorry, I am talking about Ajax scroller. Tested it in a fresh install of 3.2.0 and there the left site in the admin module keeps blank. How do I select a ad group or categorie?

AJAX Scroller, that's a module, not component.
Yes, looks like the helper JS is making problems in Joomla 3.2. I disabled it, please download the new version. For now you will see all options at once. I will make a new script to improve user friendliness in Joomla 3.2 later.

Thanks!
