OPENVPN Export Archive 0 bytes

[myksto]

I posted this thread in another section but maybe I should have posted it here.
Well, OPNsense 25.7.10-amd64
Today I tried to export OpenVPN in archive mode in: VPN -> OpenVPN -> Client Export but every user I try to export is a 0 byte zip file.
How can I solve this?
If I export using other options (File Only, Viscosity, ecc.) everything is ok.

Thanks,
Michele.
