UDFs no longer alphabetical in Selection on reports - Exclude from selection

Hi Community,

We have just upgraded a customer from V2015 Standard to V2020.1 Advanced and I have noticed that the UDFs in the selection grid on reports are no longer in alphabetical order - we have a couple of UDFs (12) but in the selection grid without them being alphabetical it makes it kind of hard to find or have to scroll - takes time.

Does anyone have any ideas or suggestions on this.

Also, there is a new button in the UDF field - exclude from selection - does anyone have any ideas how this works as I can't seem to be able to exclude any of the UDFs from my report selections.

Thanks for any help!
