TOPIC: Cant find string for Select Category

Hiya,
I wanna publish submission form to my all registered users (never used before) but cant find a string for "Select Category" and "Please select an item in the list." see attached pic.
I've found a COM_HOTSPOTS_SELECT_CATEGORY="Select category" string in hotspots.ini (line 260) in the administrator/language dir but the form is still in english and couldn't find "Please select an item in the list."
Any help appreciated

Hey Gergo,
Unfortunately I've hardcoded this in the models/form/marker.xml file... I just fixed this and the fix will be in 5.1.5 later this week.

Cheers,
Daniel
