Tremolo overlapping note?

Please see screenshot... In a piano score, I have a tremolo occurring in each hand in the same measure. The RH tremolo looks fine. But the LH tremolo is overlapping one of the notes. I cannot fix this for some reason. The tremolo will not change it's horizontal length at all, although the left and right edges can be moved up or down to change the slant. I am using Musescore 4.4.4 on Windows 11. Please help and thanks!
