@hitman3043 seem that you're using this extension: https://github.com/mageplaza/magento-2-seo-extension. I think it's better if you open one issue on its Git module.

[mbrinton01]

@hitman3043 for support with this extension, please contact mageplaza directly on their GitHub.

@hitman3043 Disabling and deleting a module won't completely remove it. You have to clear your cache pub/static var/cache var/page_cache var/generation

@hitman3043 If this was because you removed the extension, I also had the issue. Had to delete rows in the eav_attribute table.
