Weird one bar delay on audio

[ThisIsNotTheMusic]

Hey all, I'm trying to work on a remix comp for Lorde's Homemade Dynamite (look up the comp on triple j unearthed), but I'm having a weird issue when I copy the stems over to an audio track lane, in that the audio will not start until one bar has passed. This makes editing and mixing virtually impossible. I had a song saved, noticed the issue, created a new song file, and as soon as I copy a stem over the problem occurs. Any ideas? Thanks.

Does the problem still occur if you import the stem into a new/blank project?

If so, there may be some compatibility issue with the stem.

Yes, that's exactly what I did. What is odd though is that if I start with a blank project and import the stems, the song plays corretcly, no delay. At some point after I'm adding other tracks the delay occurs. It is very frustrating.

are you using glitch on the master by chance? or any kind of device that has a buffer?

No, there is nothing added to the default master. It's really weird as the instrument tracks I've added all play immediately then the audio track with the stem comes in at one bar on (all the audio tracks I've copied the stems onto behave this way). I'm close to giving up on this TBH.
