I suspect at least part of the problem is lies here: https://github.com/lbryio/lbcd/blob/6b0e7592c6e136611caae04831a36db432cc1c39/rpcclient/chain.go#L488

There was a catch-all "Lbcd" version added at some point, and it doesn't count as "Post19". So "Lbcd" falls into the default case (not displaying softforks).

[roylee17]

Looks like it should unmarshal both fields instead for post19 instead of only one of them.
