problem when SAVING a S3 Database File

[PiCo]

I'm using KeeAnywhere on Keepass ver. 2.49
KeeAnywhere version 2.0.3
To pen a DB file on S3 Account
S3 Accountcheck: OK
Opening Database File: NO PROBLEM
When SAVING the file - after edit something I have an Issue regarding the file is corrupted - see attached image

The file I'm sure that is correct and Have no problem.
ONLY Saving the DB cause the issue.
I think that the format s3:////S3 Account///DBFILE.kdbx is not interpreted correctly by KEEPASS
P.
