HikaShop - Transactional Emails, Market: Vendor Registration

-- HikaShop version -- : 6.4.1
-- HikaMarket version -- : 6.1.0
-- Joomla version -- : 5.4.3

Hello

I'm still validating transactional emails, specifically regarding HikaMarket, Market: Vendor Registration.

I've registered a new seller in the e-commerce platform and I can see that messages are being sent to both the e-commerce administrator's email account and the registered seller's email account.

The problem is the email template used to create them. I've configured a custom email template, which I use for all transactional emails. However, in this particular email, I can't see the preview; it's not working. Most importantly, the emails are reaching recipients using Hika's default template instead of my custom one.

Where can I check to correct this error?

Thanks!
