We’re putting the final touches on our new badges platform. Badge issuance remains temporarily paused, but all completions are being recorded and will be fulfilled once the platform is live. Thank you for your patience.

The elastic support would tend to cancel out the pressure load.  Is the pressure load supposed to be carried at the bolt holes?  If so, a remote displacement in UY could be used at the center of each hole instead of the elastic support.  Use deformable behavior to prevent non-physical thermal stress.  (The warning message can be ignored.  The program isn't considering the role of the elastic support to prevent rigid body motion.)
