The SH3135 doesn't have a central oscillating screw retainer, you maybe referring to an ETA based movement.
There have been some reports of the same issue with this movement, which was well known with the SA3135, but now looks to be effecting the SH 3135 movements, there is one gear in the auto wind bridge which is the culprit, many people replace the entire auto bridge for gen, but once again, there have been mixed results in these being compatible.
What I suspect is the factories are mixing the batches of SA3135 V2 movements with the SH3135 movements.
Easy way to tell a V1 SA3135 to a V2 SA3135 is the sten thickness, the V1 has a very thin tube.
