Antminer L3+ blocks vs PH blocks

Hey all,

Relatively new to mining with an Antminer. But found them pretty easy to work with!

Wondering though, why does the Antminer interface tell me that I have found blocks but my PH account doesn't?

At the moment my antminer says I have found 3 blocks since I have been online but nothign on PH.

Any ideas?

Cheers
