custom views has always been a tricky thing in FM. due to some colums are records and others are flags, records can be adjusted and flags have a set width from properties. so it now and then seems like the sizes are all over the place
you can either use the auto size colums.
or as you have saved the view, i would delete the current one. then go to preferences, clear the cache, reload skin and then import the view again and see if that might help
