Hey there! If it's showing up fine on Equifax and Experian but not on TransUnion, you'll wanna reach out to both the bureau and the furnisher about that. You should take a peek at the full tradeline and compare what's being reported across all three.
Just make sure you're checking the right version f your report skip those summaries from third party apps. Once you spot what's off, you'll have a clearer idea of your next steps.
Don't just assume all the bureaus are getting the same info they often aren't. And if something's missing or not quite right, that actually gives you a bit of leverage!
