Plugin updated to 5.x but not listed on

I think I followed the instructions correctly for updating a plugin to Matomo 5. But it’s not a listed version on - only Matomo 3 and 4 version is listed. The repo for the plugin is here: - what have I missed?

Seems to be an UI bug - using the API:
curl -f -sS "" >
It works, the Matomo 5 version of the plugin is downloaded.
