It is definitely not in the logging for the Instruments case you sent so I’m not sure how to proceed when I can’t replicate it (I’ve run it with every example of challenging audio that I have and I’m out of ideas for how to get it to happen – this was an issue with much older OpenEars versions but a fix was added for it, so this is a bit mysterious, especially in combination with it being due to a 3rd-pass search in your previously-sent logs and then apparently still happening when you turn off 3rd-pass searches). Can you create a full replication case according to this post, that you can run and see behave in the same way:

And send me a link via the contact form? Thank you.
