I have 3 addresses, in list 2, derived from the same seed. The seed is short, and have 1 to 8 digits

weeks ago downloaded 2.5.2 and claimed with seed translated to compatible format, and filled with 9's to complete 81 characters

some days later, downloaded 2.5.3 and claimed with seed translated to compatible format, but without filled with 9's.

maybe repeat claim several times. I can't remember.

Right now I've downloaded 2.5.4.

Loggin with new seed.  I can see 4 transfers of 0 Giotas to my wallet.

Total Balance: 0Giotas

¿What happened?. ¿Did I something wrong?
