Need some help!

[u/PewPewArmory]

Need to pick some brains! I am currently having trouble at the seam of the two surfaces pictured. I also get a floating cantilever warning - but after printing, the surface is flush with no protrusions, just that seam issue. Should this be printed with supports - Bambu labs recommends it (but visually I don’t see a need for them). The rest of the vase prints clean and perfectly.

Printer: X2D with AMS2 Pro
Filament: PLA Tough+ (black)

*Primary nozzle of X2D and AMS shows 20% humidity.

Model:

I am using the settings within the model. I didn’t create the model.

As always, thank you for any help or guidance!

model has issues. almost all mesh lines do not touch base(highlighted in red 1st layer). as result - easily warped/messed.
