No parasites, it happens if added to the default DBW.
You should then end up with at least 3 Slots having this issue.
I can't recall exactly, but I extracted DBW content and started
browsing the hier.hims. Seems I just adjusted Hier.him, from
the date of change my Explorer shows.
I also tried go arounds, i.e. found Eperviers 4,09 less buggy for DBW than original Mod.

I can look up my HD if I find the spurious He111 4.10 version fixed, but there's no guarantee,
usually I don't keep unused stuff.
