BambuStudio treating bridges as overhangs?

Hi all:

I am attempting to print this from MakerWorld, but constantly have the middle pieces droop and separate from the multiple passes each one has. I took a closer look in BambuStudio and see that the slicer is treating them not as bridges, but as overhangs. Is there a way to correct this? Since it's seeing them as overhangs, none of the bridge adjustments have any effect, and I'd like to up the flow in addition to slowing the print (for overhangs there is no independent flow adjustment).

Thanks!
