I was able to reproduce on self-hosted, running 2026.1027. I made some test files that were manually tagged, uploaded them to a channel, then downloaded them. All of them got stripped to some degree. Note that this happens on the server, so the client version shouldn't matter here, but I'm using Linux, Stable Desktop 2026.1017.133957, Web 2026.1026.223737.
I don't think this is technically a bug though, I think it's the feature working as intended, which is why I put in the previously mentioned feature request because in some cases you want that data to be preserved.
