I believe I found a fix to this. After months of ongoing back and forth between Chase and Quickbooks, I decided to try disconnecting my bank feeds from Chase to Quickbooks and I downloaded a small range date for each of my previous connected accounts for two day time frame. I uploaded each CSV file to QuickBooks. Once I saw the transactions displaying with numbers and not XXX.. I then "Excluded" the transactions as they were duplicates, however after I excluded them I reconnected the automatic bank feed for transactions to show automatically, and FINALLY!!!!! As the transactions have been populating in each day, I no longer see XXX anymore. This has been processing normally for 2 weeks now without any problems! 

See the attachment for proof! I hope this helps everyone who has been as frustrated as I've been for months!
