I created a category called "CA peaks", and then tried to rename it to "CA Peaks", and I get "Unexpected problem". Even exiting and restarting Locus does not fix this. I can rename it to "CA peakss" though. I get the same error if I try to rename "CA Peaks" to "cA peaks". And, if I try to rename "CA Peaks" to "cCA Peaks" the POI category just disappears, with no error message
Not that big a deal (especially at this point, since I have not imported any POIs into the category), but I thought I would report it.
