openvpn CSO not working again after updating to 23.7

[tm77nrj]

Hello,

I have updated OPNsense to 23.7, everything went smoothly.
After a few days, some of the VPN users started complaining that their CSO settings are not getting applied.
In the GUI everything is fine, but when I look into /var/etc/openvpn-csc/1/ , I saw that some of the files have vanished.
I tried changing something in GUI at CSO section with hope that the file will be regenerated, but no luck.
I tried chmod 777 /var/etc/openvpn-csc/1, maybe some process does not have permission to write in this folder, no luck.
As workaround I manually created a file for a specific user, and openvpn successfully used it at next re-connection.
I'm using OPNsense 23.7.4.
Also the last backup before 23.7 contains the CSO settings in the xml , after the openvpn section:
</openvpn-server>
<openvpn-client/>
<openvpn-csc>
<common_name>user-name</common_name>
<description>user-name</description>
<tunnel_network>10.11.11.3/24</tunnel_network>
<ovpn_servers>1</ovpn_servers>
</openvpn-csc>

The backup after upgrading does not contain any openvpn-csc lines:
</openvpn-server>
<openvpn-client/>
</openvpn>
<ppps>
<ppp/>
</ppps>

Does any one else encountered the same situation?

Thank you!
