Redmine

since I moved to redmine 3.0, I'm getting strange duplicate rows in the activity list. I first thought it was only impacting the project where I've enabled redmine_agile plugin but in reality it impact all projects.

I've tried to search in redmine existing defect list but with no luck; I've looked in the database and I can't see duplicate rows, so I assume the display is duplicated at runtime.

any though ?
