Invalid Logs in FFLogs

I have a problem, the problem is that if I want to parse old content (Titania, Garuda-Ifrit Savage) it says “Invalid Logs” but if I parse savage or extreme content from the current tier it works so I don’t understand why it does that please help :’(

You can’t rank with Echo.

If what you’re telling me is true then I feel like an idiot xD
