I think this is all coming from the flap hinges. The hotspots on the leeward part are sparks from the sides. They fall that direction since the re-entry is applying some drag.
The intentionally missing tiles were just on the engine skirt section IIRC. So this isn’t necessarily a problem with the main heat shield. The V2 flap design might mitigate it completely. We can’t really say much from just one (alleged) image.
Edit: The IFT7 stream stated SN33 has missing tiles spread over the entire heat shield this time.
Edit2: Not going to see anything from IFT7 re-entry.
