Polylang filter

I have the most up to date version of polylang and it all works fine in pages and posts . However when i use the portfolio page I get duplicates of the portfolio items (ie i will get the items in both languages on the portfolio gallery).

I am using a theme called evermore and i have sent the support team there a similar post – however if anyone else has come across this and knows which php template I need to edit I would be grateful.

Thanks in advance
Gavin
