Index not using the corresponding template

Versions (relevant - OpenSearch/Dashboard/Server OS/Browser):
2.11.1

Describe the issue:
I have an index template that specifies the index pattern of qmba-fsfqqu-*
The have indices with the names
qmba-fsfqqu-u12509_full-20250317
qmba-fsfqqu-d835c000_full-20250219

Index qmba-fsfqqu-d835c000_full-20250219 uses the index template and index qmba-fsfqqu-u12509_full-20250317 does not.
What would cause this? Is there an api call I can run that will tell me what index template is associated with an index?

Hi @CarolynR, what is the "priority" setting for each of the templates?

Best,
