No Demo and Ghost in Client. Wrong Name after rank1

[RedPig]

Hey, i played today the race map g6 and i got a dc so my rank is (1)RedPig. That not a big deal for me but i dont like to race it again and take 2 places on rank 1-2. Thats not beautiful
Im happy if someone fix this

The other issue: i trained the last 2 weeks the Race map get_50 and i got finally my pb with 24:58 min. But the client dont save the demo and the ghost.
I think this happen because i got 8 other "fail" demos for this map and the ddnet client was thinking the time wasnt better this time and dont save both. Maybe a problem if i use other clients on the same pc over the years. You think i can fix this if i delete all other demos and ghosts?

Thanks for the help and maybe some grammar tipps
