I do a fair amount of mxl tranferring. Very often, when there is an xml rendering error with meter, I make sure that the time signature signposts are visible (View>Signposts), select one of the red “x” signposts, execute select more a couple of time (ctrl+shift+a for me) and press delete. There have been cases when those rogue meters appear on locally on different staves as well. After deletion, I re-enter the required meters.
