SSRS Report not honoring month?

This is a question regarding some basic SSRS subscription settings.
I have a report that is scheduled to run the last 3 days of June of every year. This subscription has been around for a few years and not really touched since.
This morning, it fires off the report. I am scratching my head trying to guess why it would have executed, considering the history of it working reliably in the past.

In the SQL job associated with the subscription, I did notice it say’s “Of that month”, which is slightly concerning but it’s consistent with other specific month-based subscriptions

I verified the server time/date is correct.
Has anyone seen this before?
