what the problem on this

I believe after formatting the sd card is named by the serial number of the card, but it's normally just numbers and letters (from my own experience)
Try formatting in a pc and see if it shows as same once reinserted.

but previous when i format using my xperia m4 this type of name does not appear.

Yes, which is why I recommended formatting in a different machine to check
