Hello,
You don’t need plugin activation if it comes bundled with theme, read here please https://help.market.envato.com/hc/en-us/articles/213762463-Bundled-Plugins
Some plugins may ask for a purchase code for registration/activation once installed, however, you can simply ignore these messages as bundled plugins do not require activation or registration. The plugin will still work as intended with the theme once the theme has been activated/registered.
If you use annual import you should not have any error. Provide us with video on how you import templates that I provided. You can use Recordit tool to create video and share.
Regards
