Double digit numbers above Multi-measure rests are separated when converted to PDF

Hello,
I downloaded musescore 2 yesterday and it is great! One small but annoying problem I am having is when I convert a finished file to PDF, the numbers above a multi measure rest will be separated. For example, for a 26 bar rest, the multi measure rest will appear thus: 2 6. They appear nicely in the musescore file. The method I use to convert to PDF is to simply add ".pdf" after the file name. Perhaps there is a better way of doing this which will eliminate the error? Or do you think it is a problem with the PDF rather than musescore? I am using windows.

All the best, and thanks again for the improvements.

PS. The two digits are actually further apart than they appear above.
