Many problems after import

So I had two separate websites. Main site was Woocommerce and the second site was just for a blog. It was recommended to me to have the blog site as part of the Woocommerce site. So, I used the built in Export function to export all posts from the blog site and then installed the WordPress Importer on my Woocommerce site. The import was kind of successful (just missing some of the media files). I thought I had fixed the issues by uploading and assigning the media files.

Other significant information. Both of the websites were/are using the Astra theme with the paid version including Spectra. Both websites were/are using the Pro version of SEOPress.

The problems. Not sure what is causing this and support from both Astra and SEOPress are trying their best to figure it out. When I Edit/Save any post, I am getting these errors:

“Updating failed. meta._seopress_titles_title is not of type string.”

OR

“Updating failed. meta._uag_custom_page_level_css is not of type string.”

Needless to say, it does not save my changes. There is no rhyme or reason to the posts that are affected by these errors, but it is most of them.

How do I fix this?
