sm_synced very large

Hello,
I’ve been looking in the WP_options (after seeing a decrease in load time on the site). The option “sm_synced”, is auto-loaded everywhere – and currently is almost 2MB (!!!), which is an impact on the system u don’t want.

I’ve found the code – relating to files that needs to be registered. Currently it’s only populated with Backup media from ShortPixel; which is already offloaded to Google Cloud (integration is turned on). The files do appear in Google cloud The complete list looks to be populated in the following order:

ShortpixelBackups/wp-content/uploads/2018/08/filename.png”;i:975;s:80:”ShortpixelBackups/wp-content/uploads/2018/08/filename.jpg”;i:976;s:80:”ShortpixelBackups/wp-content/uploads/2018/08/filename.jpg”

Few options to fix it that I could think of, but maybe you have a better idea?
– Turn the autoload off in WP_options
– Clean /empty the field (don’t know the impact?)
– ???
Could you please advice, I see it hapening on a different set-up and domain that we have as well (also having Shortpixel & Stateless).

Loving the work and features for the rest btw!
