Plugin message on Google

Hello,
I use your plugin, that I like very much, on my website in Italian language
https://www.tvitalianaestero.com/
I used it especially during creation of the site, and I put it in “Coming Soon” mode.

Then I deactivated the function, but when I put “site:https://www.tvitalianaestero.com/” on Google, to see all the pages that were indexed, I see “Get Ready… Something Really Cool Is Coming Soon”.

But I see that only on a few pages, example:
https://www.tvitalianaestero.com/guida-metodi-per-vedere-tv-italiana-dall-estero/
https://www.tvitalianaestero.com/vedere-tv-dall-estero-con-connessione-vpn/
https://www.tvitalianaestero.com/vedere-tv-dall-estero-con-modem-router-vpn/
https://www.tvitalianaestero.com/vedere-tv-dall-estero-con-digitale-terrestre/

but also other links.

I wanted to ask, is it correct to deactivate the “Coming Soon”, or should I deactivate the plugin fully?

I don’t understand why the “Get Ready..” message was registered on Google, while I have used the “Coming Soon” mode all time when I built the website, and also why after deactivating the feature, it appeared on google on all pages.

Thank you
