Cubase 15 Score editor "Violin instrument type" keeps reverting to "Fidle" type

Trying to create the violin part, using a violin instrument type. It keeps reverting to the 'Fidle" type. Also manual slurring tool does not seem to work for this instrument. Have to tweak note lengths for that.

This is a known bug.
They are working on it..
