A few of us have reported this on GitHub here:

https://github.com/magento/magento2/issues/11163#issuecomment-333800082

However, it looks like we're stuck until they can replicate it.

I've managed to replicate the issue on 3 Magento 2.2 stores installed on various environments so far.  The problem is clearly related to google/analytics/active and google/analytics/experiments values set to true.

Mine pull request concept for the issue https://github.com/magento/magento2/pull/11205

Thanks guys. It works When i turned the 'experiments' option off.
Lets hope there Will be a permanent fix soon.
