It's good to see you here, Sean.
If you have a Paypal entry that gets recorded differently in the system, you can re-import them manually. For now, let's male sure that the multi-currency feature is turned on in your QuickBooks Online account. This will make sure the system detects the actual currency to record.
To manually importing the transactions with corresponding currencies, refer the the steps on this link. This helps us narrow down the cause of this unexpected behaviour. For your guide, check out this article.
Visit us anytime if there's anything else you need with the banking feature or categorizing Paypal transactions. I'll be right here to help.
