How NOT to Mitigate Financial Issues in a Security Clearance Case

In 2015, I was late on my mortgage and car loan about 4 times not exceeding 30 days. As soon as I got a job, I became current. I forgot to mention that on my sf86 but when I had the interview I told the investigator about my mortgage loan and that I didn’t remember how many times I was late. When he called me two days later to update some info, I also told him about my car loan…and he said, that didn’t matter. He only wanted the mortgage info. I gave him estimated dates of when it happened. Is this an issue? It was so insignificant that I forgot about it. Honestly.
