Elements Has Tons of broken Google Slides Files

Pretty much every Google Slide presentation I’ve downloaded from Elements has “unsupported placeholder” errors throughout. Which means images cannot be placed in any of these areas which pretty much makes every one of these presentations useless.

Example: https://elements.envato.com/hexagon-multipurpose-powerpoint-v165-Q4WNTU7

Also, any area that is supposed to support images that doesn’t say “unsupported placeholder” still doesn’t allow images to be inserted.

This makes me so upset as I have purchased 2 Google Slide Presentions with this broken message and no images able to insert. WHY WHY WHY? How do I fix it I have emailed both providers no help. Don’t buy Google Slides from Envato there is no support.
