Well, it appears the problems are fixed. After upgrading to 1.1.11rel it seems the problem with arrows on the map disappearing is fixed, as well as the admin password resetting back to 'admin' all the time.
I have noticed also I get a lot more connections in and out, and it seems to make it faster and more stable.
I will give it one or two more days to see if the admin password problem is fixed. I will post back here only if there is still a problem, so if you see no other posting you can assume it worked.
I am a bit confused why such a simple solution got not a single reply but hey, I figured it out anyways.
I appreciate the hard work the DPR team has put into it's products 😀
