Facebook Catalog Issues - Microdata Not Recognised/Read

[Kisse0]

Hi All,

Trying to setup a Facebook Catalog, but it seems like Facebook is having issues reading the Microdata of any of my products.

Prestashop version = 1.7.8.0

Site = https://lovefromhome.com.au

Product URL example - https://lovefromhome.com.au/balkan-nights/260-croatian-decorative-glass-bottle.html

When checking the FB microdata debug site - https://business.facebook.com/ads/microdata/debug it doesn't seems to recognise anything.  

Checking the Developer Tools I can see all the tags that are needed (I think)

Strange thing is, if i keep checking a product URL on FB debug it eventually picks everything up (have to keep trying/refreshing 20 times).

Have flushed Litespeed + Presta cache but doesn't really help

Not too sure what else to check/try.

Any help is appreciated

Thank you
