[Bug]: Split SEQUENTIAL flag lost when project files reloaded

What happened?

When I open a file (via menu open project) where a node is set with split and sequential, the sequential option is lost. this happens in the subgraph node and the Ollama node (those are where I have tested it)

What was the expected functionality?

Expected function is that the sequential flag you be maintained across save / load
