Multiple sequence setdowns being called in PremierePro

[Lekha29422377akpk]

I'm using the AfterEffects SDK to create a plugin for both AfterEffects and PremierePro.
I save the project data in sequence_data.
When the project reopens, the data is loaded back from the sequence_data. This works fine for AfterEffects, but in case of PremierePro, sequence_setdown is called multiple times, and flatten is not call before the project closes.

However, if I set this flag, PF_OutFlag2_PPRO_DO_NOT_CLONE_SEQUENCE_DATA_FOR_RENDER, then it works fine for PremierePro as well. All the sequence_data is coordinated properly then. But the SDK advises against setting this flag. Also, my renders get slower if I use this flag

Frustrating!

Please send us your plug-in, and step-by-step instructions we can follow to see the behavior you've described.

Hi @Bruce Bullis 
I have sent a mail with the code attached.
Also sharing the code here https://drive.google.com/file/d/1gR4Pn1IO147bRmor3YfANoEaINYyOqFs/view?usp=sharing as it is just the template skeleton project from the AfterEffects SDK where I have added a sequence-setup and a print to know the command being called.
Please let me know your thoughts.
