When I start to work on my parts from the score, I often like to set my own-preferred bar lines, especially around a multi measure rest. I get it all set using the Measure tool, and when I go to print, the bar lines will "jump" back to a prior setting, not to where I wanted them to be located. Finale wants to treat a multi measure rest as one measure, at times. This tends to make some measures very long or very short, not the way I want the part to look!
I know there is a way to lock them in older versions of Finale, however, I cannot seem to find this feature in Finale 27.
