Google XML Sitemaps Modification //feed//feed//feed issue

I have added new modification Google XML Sitemaps – all seem to be working fine but google throws “Alternate page with proper canonical tag” ERROR for thousands of links. They all look like this

https://jkmoto.ie/product-category/parts/engine/engine-cooling-system-engine/cooling-hose-kits/?_cat=Suzuki&_year=2007&_make=600&_model=GSR+600/page/2//feed//feed//feed//feed//feed//feed//feed/

All end with lots of //feed//feed//feed//feed/ a the end – I’m assuming that’s the issue there.
Did I make a mistake somewhere in modification or am I missing something ?

Also is it possible for links to look like this ? and have no lots of feed feed feed at the end ?

I think I did see this mod to make it look like this but can’t find it again. This (I think would be more SEO friendly)

Thanks in advance.
