B1/b2 extension after reentry

Hi Anil - last year during covid my mother was with us and we did extension for 6 months… the case was pending and we left to India along with her . After 4 months… we reentered along with her… there was no problem in the port of entry with just minimum questions like return ticket for her… after we reentered she got her bio metrics appointment and we went and gave it and they send one more notice asking us to appear again and this time also the finger prints did not come well …
how to handle this ??
Also considering her age we are planning extension for this trip.,

Is that ok ?
