Slurs/Ties Stretch to a Different Note

What I know happened:
When I want to tie two notes of the same pitch, I use the new tie button to add that tie; it ties to the next note normally with no problems. Sometimes, after working on the same score elsewhere, I come back to the tied notes to see that the tie as stretched (often across to the following pages) to a different note of the same pitch. This does not happen to all of the ties; the issue is not completely random, though: ties at the same measure/with the same rhythm are simultaneously messed up. This also happened to a certain section of the score (I have a similarly scored portion in the same score that was not affected). To correct this, I can delete this tie and redo the notation and it ties normally again with no problems. Obviously, we would want to correct this issue if it's prevalent with other users.
What happened between the time I notated the tie and came back to see it changed:
I changed the score view from Page View to Continuous View and back. I'll try to test this soon once I have time.
I (may have) changed the score from Concert Pitch to Transposed Pitch and back a couple of times. Also needs to be tested.
Normal editing etc. of score, including deleting measures; no instruments deleted/added and the part of the score that was affected was minimally edited, if at all.
Does anyone else have this issue? I don't have a score with the current problem or a photo (I fixed the score to correct the problems); if it happens again, I will update you guys. Thank you!
