Pick one keeps saying invalid

I dont think so as I’m working on my company’s laptop. I think there might be some data privacy surrounding that. But I can explain what’s going on. It’s very odd. I have a pick one question and have many text data entry fields. When I insert all of the correct questions it functions as normal. If I were to leave it empty, it functions as normal giving the incorrect feedback layer. If I were to type a single letter or a few single letters functions as normal giving incorrect feedback layer. If I were to get a few questions wrong, with real words or go through the test realistically but get a few answers wrong, it says invalid answer: you must complete the question before submitting. It is very odd.
