Checkboxes unchecked

I have just compiled an existing program using 2019 r3.1 and all the checkboxes that were set as checked for initial state are unchecked after the program is compiled. Has anyone else come across this before and found a work around? I cannot seem to change this behaviour.

Workaround, in Open event:

me.VisualState = CheckBox.VisualStates.Checked

we need to wait for next update, 3.0 had it too.
