How to align bars after deleting instruments from score?

Could someone help me with this problem?

On Musescorestudio 4, I downloaded a piece of sheetmusic (a score?) which had multiple instruments. I removed most of them so I was only left with the vocals and piano parts, so I know which piano parts to play during which vocals. However, now there are only 2 lines (one for the vocals and one for the piano) parts of bars on each page, leaving a lot of white space on the page (see file for example). If I download and print the document like this, I have like 21 pages, even though if all the bars aligned one after the other, it would all fit on like 5 pages.

How do I algin the bars of the remaining instruments?

All info is appreciated!
