Polylang and All in One Seo Pack sitemap

Hi!

I’ve found out that my sitemap.xml stop outputting the page translations.
I’ve made some research and find out that it happens because of setting aiosp_sitemap_rewrite.

When it’s turned on there is no translations in the sitemap.xml, but when I disable it – they all appear!
So my question are:
1) is it ok that it’s working that way? seems not, because I want dynamic sitemap and it’s comfortable when it’s generates automatically.

2) If it’s ok, than I should to know how to update the sitemap.xml when I add some new posts or pages, etc.

Thanks.
