Hi,

I'm using the Query String Filter web part to filter a couple libraries on a page, and using the query URLs in the quick launch navigation. For the most part this works fine and there is no issue, but on some occasions the query string is doubled after applying the navigation changes.

i.e. - /sitename/pages/pagename.aspx?query=example

becomes

/sitename/pages/pagename.aspx?query=example?query=example

Usually I just wait a bit and try again and the issue seems to resolve itself, but wanted to check and see if there was a better fix.

Thanks

I also have this issue. But waiting and trying again doesn't resolve this.

 same here in our SP2013 environments - in fact, some of the links are working and some of them duplicating the query if the link is saved.

any other solutions than waiting for an autosolution of this problem?
