Hi there,

This sounds like an issue which is fixed in our upcoming update. If you PM me your invoice number I'll send it over to you right away

All the best,
Joel

I find Easy Save update in 5.13.
I don't know how to find my invoice number.
If version5.13 didn't fix this issue, I'm fine to keep checking the asset store and wait for the 5.13+ version.
