Adding FLstudio exports automatically timestretched to fit project tempo

Adding media to project is now automatically timestretching them to fit project tempo??? Can anyone confirm this, because that is what is happening here, and I absolutely loathe it! I'm sure it must be optional. My timebase is set to time.

False alarm! I was importing files from FLstudio in Reaper, and they have "Acid Chunks" encoded into the file. I suppose that Reaper reads, and stretches accordingly. Anyway to disable that?

Anyway to make Reaper ignore Acid chunks?
