Item.name / name missing - error (Prestige Theme)

[Michael_Gladhud]

I am getting this error in Google Search Console and have tried to search for solutions.

I can not asses how bad it is and if the products don't show on Google at all or..? 350 elements seems to be in conflict (google).

Also, I need a solution or an app that can change this on all the products that are affected. I can do a tiny bit of code. But how ?
