Hello HCP, thanks for your help

The result of listaddressgroupings is :
11:58:26
listaddressgroupings

]

But bitcoin core is not totally sync.

I try the other one and i have my .txt with many adresses but not the ADRESS what i want ...

Like i say : " i send it at the same BTC adresse but when i open Multibit the adresse had change and i lost my fund because i didn't take the private key before"

I heard that after 100 adresses created the wallet recreate new adresses?? i don't understand how it's work
