I had the same issue, I think they noticed that we are inadvertently/Intentionally creating the accounts so they factor that in when setting up P2. Before I heard you had to wait months for them to reset it and now I've seen comments where they load it to the same account in 2-3 days.
In my case I sent a webform to let them know I created an account when I was applying for PR but they replied long after I got my eCoPR and said the situation was not an issue and they were aware of the account.
Now most people have to apply via the PR portal as well. So the account creation is probably no longer an issue
