Are you using Chrome? I cleared all my rules, then added it again, still the same bug.
Edit: It's also happening on other sites, maybe it's not your fault, but the extension's.
Edit 2: I've found a better solution:
FasterChrome. Seems to work with almost any page, no need to add rules. However, if it doesn't work, you won't be able to add, aswell.
