Ralph,
The track plan violates the poorly documented rule that there can only be one direct connection between two neighbor blocks.
In your example, the loop blocks at each end have two connections to the turnout blocks via the normal and diverging legs.
The each loop needs at least two blocks. ?You also need intermediate signals at the new block boundaries.

Subject: [jmriusers] SML for Reversing Loops
Date: Friday, March 28, 2025 3:52 PM
I constructed a simple layout editor panel with two back to back reverse loops. The "auto generate signaling pairs" only created 1 pair. I created the other 7 manually and did enough sanity checks (occupancy and turnout states) to convince myself that the signal aspects work as expected. Is there a problem for JMRI signal pair recognition in this somewhat strange configuration or am I approaching the problem incorrectly?
?
I uploaded the panel file to a problems being worked on folder, Snorkel, if someone is interested.
