Sub categories not syncing to online store

[Inception]

The Subcategory feature does not seem to always sync over. Is there any particular reason why that I am overlooking?

Hey there, @Inception - 

Welcome to the Community. 

Could you give me a little more insight on the error you're seeing with the sub-category sync? And how you have those sub-categories set up? 

I will keep an eye out for your reply👀.  Thank you!
