I have entered c am f g in the chords window and put a rest on the f by entering F. but nothing has changed, what am I doing wrong please?



On my system the F. (prints in Red text) and causes that entire Bar to be silent. Just as in C \ Am \ \ G

Try sitting on this bar and R-Click - Select Chord Settings and you will see the exact setting for the Rest.
