One way sync with do not delete option set is deleting files

Overview

Windows desktop 3.33

Issue

I have a backup folder setup to sync to the encrypted side if the id server. i do zipped backups to this folder. the backup sw i use only keeps several weeks of backups and deletes old zips.
so as to keep olde backups on ID only, i use the DO NOT DELETE option in the settings (on both local and remote).

when the backup sw deletes ONE file at a time, ID puts out an error message (annoying in itself) and does not delete the file on the server, all as expected.

however, i decided to reduce the number of local copies so i deleted a few in the local dir. ** AND SO DID ICEDRIVE ** on the server.

in the log it said:
[08.07.2025 09:46:37.658] [22144] req: batch delete 17 items
[08.07.2025 09:46:38.042] [22144] the response is: {“error”:false,“message”:“Delete successful”}
[08.07.2025 09:46:38.043] [22144] sync: batch delete succeeded for 17 items: “Delete successful”

so looks like the DO NOT DELETE sync option does NOT work for multiple deletes,

sadly, i now have zero trust in this new v3 client
