The mechanics and "Close flipper M-B relay" seems to be working correct. For the flippers to stay closed, these switches need to be adjusted correctly:

There's two NC switches labeled "Close flipper solenoid EOS" in the schematics. Adjust the solenoid EOS so that the locking claw has enough time to get hold before power is cut, and the relay EOS so that it cuts power at the same time or later than the solenoid EOS. The "Close flipper M-B RE" switch should have the smallest switch gap possible for fast reaction time.

Here's the "Close flipper solenoid EOS" switches in the closed position.

It looks like your switches cuts power too early. Try bending the non-moving blades so that the gap becomes tighter.

The close flipper solenoid shouldn't have any power when the flipper assembly is locked in closed position. Can you post a picture of the switches after adjustment (in both positions)?

Quoted from jlbintn:

Are not those two leafs always supposed to be in contact, except that momentary gap when the flippers close?

I don't think they are. That may explain why the flippers open when you first hit the Odin or Wutan mushrooms and then the blue mushroom. Odin and Wutan mushrooms trigger the open flipper relay and its holding circuit trough the closed upper EOS switches, but since the flippers don't open it stays energized. The close flipper relay then activated by the blue mushroom gives power to the solenoid just for a split second trough the closed solenoid EOS switch, but the relay does not hold in because of the open relay EOS switch. This unintentionally makes it easier for the open flipper coil to move the holding claw if there's something mechanical and/or low power issue preventing it.

Seems to be either a mechanical issue or not enough power to the open flipper coil then. Coil spring too tight? Low voltage from transformer?

Quoted from jlbintn:

Can that bigger spring cause the problem I am experiencing?

That may be possible. From the photos, it looks like yours have been shortened and stretched, which will make it too strong for the other parts of the mechanics to handle.
