Fill page with blank staves not saving

Greetings.
Working in a score with multiple flows I am setting in Layout Options Fill frame with blank staves After every flow, and it works! However, if I save and reopen the score, the option is automatically set to Only after last flow. I don’t mind changing it every time, but I would like to set it up for good as I want it to be. This also makes me think if per haps there is another setting working wrong and I am no aware of it.

Thank you in advance,
Daniel

Just echoing this post. I have the same issue using Dorico Version 5.1.81.2225. Exact same behavior as with Daniel in the OG post.
Hope we can get this fixed.
