XF 18MM F1.4 R LM WR - Very loose aperture ring

[pw-pix]

Hello, I'm new here, but a long time Fuji user. I've had an X-E3 since 2018 and also have the XF 16mm F2.8, XF 18mm F2, XF 23mm F2, XF 27mm F2.8, and XF 35mm F2 lenses.

I just lashed out on an X-T5 and the XF 18mm F1.4. By all accounts a premium lens in the latest LM series from Fujifilm.

I'm finding that the aperture ring on the 18mm F1.4 is so loose that it will not stay where I set it. The slightest brush against the strap, or clothes or my hand is enough to move it (sometimes by a whole F stop. I've had a look around on forums and have noted some people say it is looser than the other two new F1.4 lenses (the 23mm and 33mm LM), however mine is so loose that it makes the lens annoying to use and results in shots at incorrect apertures. I shoot almost always in aperture priority and have appreciated the aperture rings on the XF lenses.

Has anyone gone back to a camera shop and/or Fuji about this issue as a warranty problem? If so what was the outcome. I can't believe that my aperture ring is supposed to be so loose.
