Unwanted WAV envelopes on Reaper

[banananut]

Hi there,
I have an annoying feature on Reaper: when you are putting loops (acidised wavs) in a track, Reaper automatically put a small fade in and fade out envelope on the wav that you can only see by really zooming in (but it affects the sound with a tiny drop-out glitch effect).
In Reaper can you disable this auto-enveloping?
Thanks,

Preferences/Project/Media Item Defaults - uncheck 'Create automatic fade in/fade out for new items, length'

Thank you!
