Problem:

The Resize image option of the image block loses the custom option sometimes.

Solution:

Make sure that all the image names uploaded to WordPress do not have non-Latin characters.

It might have issues on some servers.

Problem:
Conditional display of heading if view is empty or not have any results

Solution:
What you should do is, try to add a conditional block and configure it to check with view's shortcode and further select "number of items found in view" and setup your conditional display and then move the conditional block between view's output and view's loop section.

You can find proposed solution in this case with the following reply:
