Scratchy fill layers over bridges

Hi,

I have a print in which there's a small void.  The slicer produces a gcode file that contains a bridge over the void and then the later layers are fill layers on top of the bridge.  In practice, however, the first few fill layers end up being scratchy - a bit like pillowing.

For instance, here's the bridge layer being added:

 

 

Then when the fill layer gets added on top it looks like this:

As you can see, the filament doesn't lie flat.  It sticks up so that when the next layer is printed, the nozzle scrapes against it.

 

Usually after a few layers are printed, it all smoothes out.  But it takes 3-4 layers and each time, I can hear the nozzle scratching the filament.

 

It feels like something isn't calibrated or set up correctly.  Any ideas?  Everything else looks/prints fine.
