Hi!
I might have found a minor bug: in the report edit view in the "Report parameters" section, there are some wonderful options I hadn't noticed before, one of which is 'Title' to provide a customised title for a parameter (or group if the rest are blank. I have started using it to group the parameters into logical sub groups when using lots of parameters.
What I've noticed is that when I set 2 title values and verify they display properly, the next time I return to that report edit option, the title values in the dropdown are blank - so if I save the form, it overwrites the title values with blank entries.
Is this isn't enough to replicate the issue, let me know.
