Anyway, I'm new and don't post all the time, so maybe it was my mistake.
Should I delete the post now or combine the two posts?
You can not delete your own topic. Even if toedit it and report it to a moderator, they will not legit delete it because many people have posted there already. I just saw it similar and think both can be on the same topic and it is nice that you accepted. You can leave it but just in case if next time.
