Delete time sig at the end of a line to have a finished bar rather than an open bar.

I've created a piece with very random time sigs in it because it's a mass/chant style. At the end of each line I seem to have a time sig to show what's coming on the next line.

However, whilst I can hide this I can't delete it for some reason. I'm also left with what looks like an open bar at the end of each line (except the last). When we come to print this out it looks like all the lines except the last are shorter because the bar lines don't match up and as it's going into an order of service for a wedding I need it to look aesthetically pleasing!

Any suggestions?
