Hello, I have the same issue and I contacted the developers, that answered very promptly.
They advised my to check here and it case to make a feature request.
I also proposed the same solution i.e. making it optional.
Meantime a temporarily solution can be implemented: pressing on the chord mode button on the left, in order to make the cursor advance. In this way it will behave as it was in the previous version, it will deselect the chord end it will be easier to proceed in the creation of the scores.
