is there a bug with trash function??

Hi

http://www.thegasfitter.co.uk/central-heating-services-2

I trashed the post central heating services but then created another one of the same name.

I have tried going in and editing the permalink by removing the number 2 but once the page is published it reverts back to the 2 again.

A wootheme ninja in the support forum suggest there is a bug with the trash function. Who do I report it to or what can I do??
