Problem Description

image image

  1. duplicate name in _cat/templates, but _template/web* only shows one template
  2. when a new index web_monitor_new created, it applied the old version template
  3. delete the _template/web_monitor, and re-put _template/web_monitor, all goes fine
  4. I don't know how it happened, cannot reproduce.

I suspect one of these is a legacy index template and one is a composable index template (the composed_of column in your screenshot gives me a big hint on that).

@Morriaty-The-Murderer can you paste me the output of running the following two commands? (Feel free to elide anything you consider sensitive.)

GET _template/web_monitor

GET _index_template/web_monitor

Reading the docs on (composable) index templates, I see the following:

Composable templates take precedence over legacy templates. If no composable template matches a given index, a legacy template may still match and be applied.

If I'm right about the nature of the situation, then I definitely see how it could be confusing. If you're only interested in using one of them, then we just delete the other (and leave it deleted), and I imagine that'll fix things up.
