Okay, now I'm even more confused.
I've been monitoring my TU CR daily using the free trial of TC. The TL in question recently updated coinciding with latest statement for the credit card (and extra month of "OK" activity is shown, the "reported/updated" date changed to April, and the balance changed to the balance from the latest statement), but it *still* does not include the credit limit.
Looking back over TU's dispute resolution letter, I noticed that they list a URL from which to get an updated/corrected CR for free. So, I went to their website and got it. The format of the CR directly from TU is a little different than the format of the CR from TC, but the information contained is identical (including the parts that are incorrect, such as the missing balance). The only time this TL has had the correct information was in TU's dispute resolution letter.
The primary problem seems to be the classification of the account. The CR from TU says the "Account Type" is "Open Account" as opposed to other credit cards accounts on this report that are listed as "Revolving Account". On the CR from TC, the "Type" is "Flexible Spending Credit Card" as opposed to just "Credit Card" for my other credit card accounts. Also, on the TC report, this TL is in a section for "installment accounts". The latest CR I have from myFICO.com (about a month older than the TU and TC CRs) lists the "Account Type" as "Open Account" just like TU CR.
On the dispute resolution letter that included the revised/corrected TL for this account, the "Type" is simply "credit card". Is the problem simply that the account is mis-classified by the CCC? If so, and it is not being considered with my CCs, does that mean that the lack of a balance doesn't hurt me? Does that mean that it doesn't impact revolving utilization and/or that the individual account utilization doesn't impact my FICO score (or impacts it differently)?
I plan on calling TU to see if they can shed any light on the situation, especially why the "correct" information occurred only on the dispute resolution letter, and not anywhere else.
