Gaps in support layer, even when interface line spacing is set to 0

Hi all, I have an issue in Bambu Studio where the support interface will not close up no matter what I try. The interface is 3 layers with ironing. This causes defects on the bottom surface of the model. I’ve tried changing support line widths, wall generation type, x/y distance…Nothing works.

Any bright ideas? Thanks.

Can you attach the .3mf file?

I don’t mean to sound like a jerk, but I can’t upload this model until it is protected by a registered design application.

Thanks for helping, I’m putting this down to a bug in BS. I’ve never had any other supports do this no matter how complex.

Ill be looking forward to recreeating this and selling it for millions.
