We checked this issue from our side, and it seems okay. Please disable third-party plugins and customizations (if there are any) and check if this issue persists. If you use a caching plugin, make sure that caching is disabled for logged-in users. If this issue exists, please send temporary WP access to support@hivepress.io with details for reproducing this issue, and we’ll check it (please send only the link, without login and password). You can create a temporary access link using this plugin: Temporary Login Without Password – WordPress plugin | WordPress.org.
To ensure that this issue is not caused by third-party plugins or customizations, I tested it on a clean HivePress installation running on my local development environment (WampServer). In this setup:
No third-party plugins are installed.
I am using the default HivePress theme.
Caching is not enabled.
Unfortunately, I am still experiencing the same issue. When clicking on “Change Details” on the “Select Package” page, the previously selected category is lost, while all other fields remain correctly filled.
