App telling me I'm pregnant despite having deleted test result (evap line) and having now logged negative test result

The app is telling me I'm "totally preggers!" and that I have a "baby on board". This is somewhat disconcerting to say the least given my very faint positive (there's no "inconclusive" option when logging a test and I got a bit too hopeful and put it as positive) turned out to be nothing and I have since logged a negative test on clear blue. Thought deleting and reinstalling the app would work but it hasn't. Any ideas? It's a bit upsetting now tbh.
