If it was me, I’d pull it apart and see what is wrong. Are those bolts too long?
Something is wrong
Those fasteners are not correct and may be too long.
Supposed to be M8x15mm long hex head bolt and they get a lock washer under the bolt head which will be 2 or 3 mm thick so only about 12 - 13 mm of actual thread into the flywheel. The depth of the pressure plate fastener holes decrease when the flywheel is machined.
A socket head cap screw is the wrong fastener for this application. Although they have higher tensile strength, they are more brittle than a hex head bolt due to case hardening. Even worse, it looks like you are using plated socket head cap screws which are prone to hydrogen embrittlement making unexpected stress cracking a real concern. Stick with the OE style hex head bolt as the proper fastener.
More details than you wanted to know:

Likewise step height between friction surface and pressure plate surface needs to have been machined properly
