Why the hell did you scrolled down to address 228?
Electrum and most wallets only search until a determined address. Your software probably searched until 50th or something like that, and as the balance were all zero it stopped checking.

Did you know that there are billions addresses derived from your xpub, and Electrum will certainly not look for balance in all of them.


Did you check in a block explorer if your balance is there?
Probably the best way is to manually add the public address of your 228th address to Electrum, so it will force electrum to look for that specific address balance.
