Node Revision History page

I need some help on an issue that I believe is related to this method. On line 209 the ‘#template’ property includes a string of date by username that is bracketed by {% trans %} twig filter. On my node revision pages, it just reads ‘date by username’. If I remove the {% trans %} filter it works. Any help on this would be appreciated. Thanks!
