Best choice is to rejumper the MPU.

If it's coming up in German, W18 is missing. Either replace W18, or remove W14-W17.

Either will work.

Here's a pic with a W18 replacement that I'm not real proud of at this point, but was a challenge for me when I first got into pins

I don't see anything wrong with that John, looks clean.

I've seen far worse attempts at installing jumpers into CPU boards!
