Notes starting at beginning of project in REAPER cause beginning of sample to also be played in render, ignoring offset

[Merlin04]

I have a bit of a weird bug that might be REAPER's fault, but I thought I'd bring it up here just in case. If you have a note at the start of a midi track that's at the start of your project, and samplv1 has an "offset" set to remove the beginning of the audio file, the start of that audio file plays at the start in addition to the actual sample. It functions correctly when previewing from the DAW but when rendering it out it has the issue. I've also noticed some odd behavior with offsets on all notes (it seems like the start of my sample is always getting cut off in the render) but not sure if it's related.

what you mean as differences between "previewing from the DAW" and "rendering" ?

what happens with other DAW's ? eg. ardour, qtractor, muse?
