FreePBX upgrade sound problem

Hello,

we upgraded our FreePBX Current PBX Version:14.0.13.28, Asterisk Version: 13.19.1 to FreePBX 16.0.40.11 Asterisk Version: 18.16.0.
We did it by creating new virtual machine and transfering backup from old server to the new one.
Now we have some problems with new installation.
In older FreePBX we had custom sound files in Georgian language.
Now it says:

“you are currently caller number {digit} waiting to speak with a representative, Thank you for your patience”

But only digit in Georgian, all ramaining phrase in English.
We need all phrase to be in Georgian.

How can we do that and where to put sound files?
