You mean when you try to highlight CV activities?

Can you try with a simple click activity and try to highlight, also share the workflow

Thanks

The error occurs whenever selecting multiple activities ( of any type ) by holding down left click mouse button and dragging over several activities with a highlight box.

Your suggestion of clicking activities and holding down control button to select multiple activities is working as an alternative to click& drag highlight box.

Thanks
