Those are just the scores the cards provide as part of their service. The creditwise is a Vantage 3.0 score and no lender us it when making their decisions. I would ignore that score. The other one is a Fico score and what your score is for TU.
You will want to pull all three your Fico scores. You can get a trial at credichecktotal.com for a buck and see all three of your Fico 8 scores. If you cancel before 7 days it won't cost you anything else, but if you are rebuilding then it may make sense to keep a subscription so you can monitor your progress.
I'm sure they are reporting to all three you just haven't seen those reports.
No, it does not mean your scores haven't improved with EX & EQ as well. It's just that TU is the bureau Disco and Cap One chooses to reference for providing free scores to consumers. Also -- just to be clear, Disco is providing your FICO 8; Cap One is providing your Vantage 3 -- these are two different scoring models. FICO is what is used by the majority of lenders to make credit decisions; Vantage is not currently used by lenders.
You can get all three scores with a free / 30-day trial through Experian.com to see where you stand with the other 2 bureaus. This membership plan, after the 30 days, will be $19.99/month - so you can cancel before the trial ends if you do not want to pay; with the service you get your Experian FICO 8 score updated daily and all three scores updated on a quarterly basis. The ability to see an updated score daily is great when your rebuilding if a lot of changes are constantly happening -- i found it to be extremely valuable during my rebuild as it also helps you better understand how your actions, and other events like account aging, affect your score.
You can also upgrade to other membership tiers too if you want for more frequent 3-bureau updates. Or, you can stick with their free service which provides monthly EX score updates and reports.
Wel I'm sure they have, just those two credit card companies don't report on any bureau other than TU. That said, Capital One's creditwise isn't a true FICO 8 score (the one lenders use over 90% of the time), so take what that one says with a grain of salt. Discover's is your true TU score though.

Yes. All lenders that provide a free score (be it FICO or Vantage) only do so from one of the three bureaus - even though they report data to all three. For example: Amex only offers an EX FICO 8; Citi only offers EQ Bankcard 8; NFCU and PenFed Credit Unions offer EQ FICO 9, etc.
You should find out where you stand with FICOs for all three bureaus and review all three reports for accuracy. So long as the info reported to all three bureaus match, the three scores, while different, are generally within 20 points of one another.
