Unable to use the old url with translated pages

Hi,

I had the qtranslate plus -plugin in use on my site earlier. Now I have removed it and switched to Polylang but the problem is that I am unable to save the urls with the same name for the translations as they were before. For example /en/company is now saved en/company-2, de/company-3, ru/company-4… I have checked that there are no such urls in my posts/pages and also if I try to open that en/company -url directly nothing is found. Also there are no such mediafiles saved with that name. Any ideas what I could try next?
