I'm having major difficulties with custom parameter creation in 2015 - it adds a couple of extra entries which didn't appear in any previous version, and they cause issues connecting to the parameters via ice trees.

When I create a new custom parameter set and add a new parameter, it adds two new options under the parameter name, script name and description. If I make all of these the same, and drag and drop the parameter into an ice tree, it won't read it. If I leave the two new options as default (comes in as Param, Param1, param2 etc) then it will read into an ice tree but will show as the script name, so I can't read the tree clearly.
I've tried renaming my 2015 user prefs folder, but the same thing happens, and it doesn't in 2014sp2 and backwards.
Is there anything I can do to fix this myself? Any ppg logic I can copy from an old version? Any suggestions gratefully received!
Cheers
Matt
