Hi
To be honest, we've not used that cookiebot before so not sure how it works. You can try to test with default Joomla template - Protostar if you're using Joomla 3 or Cassiopeia if you're using Joomla 4 - and see how it goes.
If it works with default Joomla template, then there is something wrong with our template and we need a closer look to check the issue, share us the admin login info so we can help you out.
