ExportGroup in Particle Export does not work.

[tomoya kimpara]

Particle groups are divided into 1 and 2 and then sent to a single event.
When I check in DataDisplay, they are properly separated, but when I export, they do not come apart.

Culling in Tycache is also not working.
I am recording a video for more information.
Is this a bug?

Thank you in advance for your help.
