parasites can be totally unpredictable, I had one disappearing from Google for 3 months and then it reappeared last week in 4th page.
In your case I would definitely wait more, and also consider that parasites can behave in more "crazy" ways compared to personal sites, so it's quite normal if they disappear more than blog post from your website.
Plus, parasites can handle more spam (usually), so 5 links even if bad shouldn't make it tank (that's only for saying that you need to wait more but your situation isn't necessarily bad overall, disappearing pages are common with those practices).
