Occasional mis-sample on print track

[Digital1]

Our studio uses a print track internally within our Pro Tools sessions so that we can QC our mixes in real time before client delivery.

Recently, we have noticed our prints creating a “blip” right at the end of spots. This happens inconsistently and fairly infrequently, but it is enough that our clients have noticed and reported the issue to us.

In the last one or two samples of a selected region to be printed, the print track will randomly pull audio from earlier in our spot, despite every track being routed into the print being completely faded out by this point. I am completely sure there are no other hidden tracks causing this final blip, especially because the issue can be solved by changing nothing within the session and simply printing the same region again, non-destructively even.

Has anyone experienced this before?

I can grab some screenshots if that would help anyone understand better.
