Render tracks offset problem

[Bunnly]

I try to render a WAV and MP3 file in Waveform 13 FREE and some of the tracks are offset which annoys me a lot. The electric piano and drums and vocals are all off and it sounds really weird in the render. Can someone help me fix this problem? It sounds perfectly fine in the DAW. Temporary fix is to offset it inside the DAW and the render sounds fine but then it sounds weird in the actual DAW.

Fixed it, it was my fault for not realizing this, somewhere near the start was offset so the whole track sounded weird but I didn't notice because I kept playing the main part in the DAW.

Out of curiosity, some tracks were offset but not others? I'm interested in how you didn't immediately notice this--and maybe it can help others in the future. Not a big deal since you obviously fixed it, but which track or tracks were off? How did you figure it out?
