Problem with ACF Field

Hello,
We have been using the Blocksy theme with the Companion Premium plugin for several months. However, for some time now, we have noticed a problem with one of our custom post types, which ultimately occurs with all post types. To explain this simply, we no longer see the “ACF Field” proposition in the content items that we were able to display before. This element has disappeared both for the global post type and for the single publication.
At the same time, we also noticed that the results filtering function (at the post type level) has disappeared.
Is this normal? Is this a conflict with ACF? This will force us to customize certain templates through programming even though we had chosen Blocksy precisely to avoid this. ??

If you can help us, that would be great.
Kind regards
