ABS bed adhesion issues

Does anybody have an idea, why I have these intermittent adhesion problems with my print sheet? The Filament is Flashforge ABS and the sheet is the one that came with the VC3. I have tried cleaning it thoroughly (soap, water, IPA) and have tweaked my Z height and bed temps to no avail. Could the PEI just be end of life/damaged at that location? Does anybody know of good print sheets for ABS use?

This looks like nozzle too near to bed in those areas. I'd try increasing z offset a little, maybe 0.05mm higher. Best done while it's printing, then you can see immediately if it helps.
