Blocks found but steal display => Block Found: Never

[binbins31]

Hello,
My pool is well started, website display well everythings. I mined several hours and steal 0 in pending balance, I was sad.
I decided to look at pool wallet and I saw 3 payments, so 3 blocks found.
The web app doesn't display blocks found and the payments associated, still "BLOCK FIND : NEVER".
Do you have an idea why ?

and I think had those errors when the blocks end to maturate or when the blocks were found :
