Curator no longer working. I think it's related to a failed ILM setup

A little while back I tried to setup ILM. It didn't go so well, I asked for help here but was unable to get it working:

So it's kind of half setup but still giving errors about rolling indexes over.

I've kind of left it as it is for now but I noticed today that curator does not seem to be working any more. Now when I run curator it reports an empty list of indexes, no matter what I set unit_count to. Here's my simple curator config:

actions:
1:
action: delete_indices
description: >-
Delete indices older than 15 days (based on index name), for logstash-
prefixed indices. Ignore the error if the filter does not result in an
actionable list of indices (ignore_empty_list) and exit cleanly.
options:
ignore_empty_list: True
timeout_override:
continue_if_exception: False
disable_action: False
filters:
- filtertype: pattern
kind: prefix
value: logstash-
exclude:
- filtertype: age
source: name
direction: older
timestring: '%Y.%m.%d'
unit: days
unit_count: 5
exclude:

And the output that I'm getting from curator:

2019-08-08 18:18:04,202 INFO Preparing Action ID: 1, "delete_indices"

Here's my list of indexes currently:

I'm pretty sure that this is related to ILM because we have 2 ELK servers that are nearly identical, 1 for dev and 1 for prod. I've only tried to implement ILM on the dev server. curator is still functioning correctly on the prod server. I don't think anything else has changed, no changes to index names or anything like that.

Because it can collide with ILM, Curator will not touch indices associated with an ILM policy by default. This can be overridden by setting the option allow_ilm_indices: true

That did it, thanks @theuntergeek!

If anyone sees this and knows what's wrong with my ILM setup I'd love some tips on that as well.
