@albertski, thanks for the report. We rely on issue reports like this to improve Drupal core.
I tested this on Drupal 10.1.x, standard install. I created a test content type with a reference field for basic blocks. I then created two custom blocks. I did not place the blocks. I then added a new node of the test content type, in the autocomplete reference block, the two custom blocks were displayed. It seems this has been fixed.
I am closing this as outdated. If you are experiencing this problem on a supported version of Drupal reopen the issue, by setting the status to 'Active', and provide complete steps to reproduce the issue → (starting from "Install Drupal core").
Thanks!
