This is very interesting indeed.
I plan on growing out his exact same strain.
I would have to say it will not mater as that is not a photoperiod plant right now.
I would keep it on 18/6 and start treating it like an autoflower at this point moving forward.
Sometimes when breeders mix in auto genetics they don't always get them all out.
Or it might have been a packaging error and the seeds in the bag are not what was advertised.
For sure reach out to
