Problematic URL's and field weighting

Hiya,

I’m having a problem with something adding #list-all to the end of URL’s all the time. I’ve searched through all the code and theme code for list-all #list-all and #list (list on its own returns too many hits). I was wondering whether anyone else has run into this and what could be causing it? Also field weighting doesn’t seem to be working correctly. Is that something fixed in Drupal 8? Thanks for any pointers you can give me!
