My USCIS online account shows my spouse’s name spelled wrong on one page but right on another, should I be concerned or is the portal just glitching again?

Yeah that’s pretty normal honestly, the USCIS portal shows little mismatches like that all the time and it doesn’t usually mean the actual case file has the typo, so if the name is correct on your receipts and notices you’re fine, and you can always send a quick secure message later if it’ll help you feel better about it.
