Multiple Soul Storms / Over 6 Stone Generators

After defeating the first Stone Generator, I noticed an extra stone generator, but after defeating 3, and finishing the soul storm, I still saw over 3 extra Stone Generators, some of which was in a different region but others the same as the first one. and was able to finished another set of 3 and rewards, and the other extra Generators disappeared once I got 6 in total, I assume the game duplicated

Locations: Within The Sift, Humbler Huskland Lullaby Hills

Observed Results:
- Two Soul Storms, but only one is recognized, both function the same except for region and UI (second soul storm has no indication it exists other than generator icons), over six generators, others disappeared after the first two Soul Storms were finished

Expected Results:
- One recognized Soul Storm, three generators
