I sliced this model once myself just to investigate. It looked correct to me, but you might want to make sure you have your bridging area threshold set low enough to capture these small surfaces. Open your FFF Settings and click on the Other tab. There is an option labeled "Unsupported area threshold". This determines the minimum area that is required for a specific region before the bridging modifications get applied. It's really useful to control where the bridging logic is used so that you aren't constantly engaging the bridging fan speed and bridging flowrates unless you really need them.
I have my area threshold set to 50 mm^2 and that seemed to capture it just fine.
