Missing faces in Unity after merging vertices

[north yew]

Hey all! I am encountering a seemingly simple issue and figured I could find help here. I am making low poly models for Unity 6 and when I export a model as FBX, import it into Unity, and drag it into the scene, certain faces are missing or possible backwards. They appear correct in BlockBench however. This appears to only happen to faces that are adjacent to a merged vertex. I tried doing some internet searching and mostly came up with Blender answers instead of BlockBench but the suggestion that they put out was to flip the normals of the face. If that is the fix here, how do I do that in BlockBench? If that is not the fix, what can I do to fix this? Thanks!

Select the affected faces, right click, and click Invert Faces

You can preview face directions via View > View Mode > Face Orientation

Ah thank you. I must've missed that option originally when I looked. I will try that and export it and report back whether or not that fixes the issue

Sothe red ones are the back of the face and the green ones are the front I assume?

yes
