HEY TUI Cannot enter the "-" in the date field

[mikeproctor]

When trying to enter a date in the TUI I can not enter the required delimiter "-" for some reason. It just doesn't show up. If I use "/" the dialog won't accept it and says the required format is YYYY-MM-DD

Just tested on my desktop and it doesn't accept the "-" in the date field either.
