Hivepress guttenberg blocks not available at alternative theme

Hi, the guttenberg blocks from Hivepress are not available when I try to edit a main page from an alternative theme. Other blocks from other plugins are available, just the Hivepress are missing. How to fix that?

Please provide which theme is on your website and we will test this theme

HardNews by AF Themes (free version), it is a child theme of CoverNews.

I’ve tested this theme locally and it seems to be ok. Please disable third-party plugins and customizations (if there are any) and check if this issue persists. If you use a caching plugin (e.g. LiteSpeed), make sure that caching is disabled for logged-in users.
