Friendlist is bugged.

My friendlist is totally bugged. All my actual friends are not listed anymore. All corresponding groups are also gone. Instead i had 3 General Groups filled with friends from ages ago (who don't even play anymore and were deleted by me) or total random names from very different regions (EUW, EUNE, OCE, ...) i never heard of. So all my friends are gone at this moment, except for one which is also not playing for 1 or 2 years now, but apparently just send me a new friend request?! Anyone else having this? Relogging did not fix anything.
