phpIPAM import addresses and update everything

Hello Folks.

I'ts been a while that I am using phpIPAM to manage my subnets. However, there is a annoying issue that bothers me since I started using phpIPAM: The xls import function doesn't update the records on PowerDNS server.

If I import the xls with records that doesn't exist, it's fine, phpIPAM create the records on PowerDNS DB, but if I import a range with new PTR records, phpIPAM doesn't update them. Worse! It creates duplicate entries on PowerDNS.

It's been now 4 days that I am searching the code to know how to fix this out without luck and I came here to ask if someone has fixed it, or at least, knows where to search.

Any help is appreciated.

Cheers
