Port Forwarding set-up on T3200M issues

[wireless]

I am familiar with how port forwarding works but recently on my T3200 M router I see a large number of entries (over 20) for port fowarding for a raspberry pi I set up these are TCP settings . I have to remove them manually. I understand the software on the pi's may be doing this but is there anyway to turn it off and is there away to delete these entries in bulk. I don't see the ability save my configuration file on this router.
