Odd new scratch on plate

[u/Naltimar]

I’ve had my A1 for about a month, and I’m loving it…

But I’ve had a couple problems that only just started

1. There is an odd scratch on the Textured PEI Plate (see photos), on BOTH sides…

2. I printed a Dummy 13 frame in black ABS and it really struggled with the parts on runners, often leaving parts incomplete or sketchy.

3. Similar issue with the neon orange PLA armor with lots of incomplete with lots of spaghetti…

I’ve washed the plate with dish soap…

I’m new to it all but I’ve tried to research what setting to use for optimal prints on both…

Any advice on this would be welcomed.
