Not fully bridging across infill but preview state it does?

Hey guys,

I had to stop a print because the print is not fully bridging between the squares but some squares are bridging.

but in bambu labs, the print preview shows it should all be connecting and bridging?

How do I fix this issue? Wasted 8 hours to get to this part to fail......

Thank you
