Multiple image optimization plugins active

Got the following message when going in the edit website:

Oops… Multiple image optimization plugins active

We noticed multiple image optimization plugins active on your site, which may cause issues in Optimole. We recommend using only one image optimization plugin on your site for the best results. The following plugins may cause issues in Optimole: Jetpack.

Not sure what to do with this as removing Jetpack seems not to be a sound idea. Can anyone assist?
