It could be a bug…
Like the slicer thinking those connected parts are close enough to not cause any overhand issues.
I might be mistaken here but based on my experience with weird bugs I might say this:
Bambu is all about speed with quality often second best in terms of consideration for print profiles.
IF Bambu made this mistake I suspect than there might be a fix after all - or a workaround to be precise…
Could it be that the slicer won’t recognise those overhangs because the LAYER TIME is higher than what it takes to make the filament curl up ?
In the filament setting check the LAYER TIME against your slicer preview 
If the problematic overhangs take longer to print per layer than the set layer time you found your problem/bug.
Let’s say the layer time is at 4 seconds.
Increase the layer time to just over what it takes to print a layer of these overhangs.
If that makes a big difference you might have a workaround until Bambu fixes things properly.
You can also play with the Cooling Overhang Threshold, default is I think 50%.
If you reduce that to less than what the layer overhang of new layer is the forced cooling shall kick in.
Meaning the fan speeds up and unless Bambu created two bugs the print speed should also go down a little bit.
