Odd problem with p2pool

I run a p2pool and I'm having an odd problem. I set it up mainly for my own use, but it should be open to the public for Dogecoin if anyone wants to try it (stratum+tcp://www.tmerloservers.com:9555). It seems to be running fine and I can connect to it and receive payouts.

The problem is I have 3 connections to it (2 from localhost and one from another PC on the local network, all 3 using different coin addresses) but they all don't show up on the static page miners list. It's random which one it shows if it shows any at all. They appear and disappear at times.

They appear to be conflicting in some way and I'm not sure where to start looking. Is it a network problem, a p2pool problem, a miner problem or a wallet problem?

If anyone has any idea where to start looking I can supply any info you need.

Thanks!
