      I was not able to get a calculated item to work correctly.

      The server log outputs the following line:

      3347007:20181011:103327.080 item "csdra-s46:tomcat.globalrequestprocessor.requestAverageResponseTime" became not supported: Cannot evaluate function "last()": item "foohost: tomcat.globalrequestprocessor.processingTime" does not exist.

       

      The calculation form 

      last("tomcat.globalrequestprocessor.processingTime")/last("tomcat.globalrequestprocessor.requestCount") / 1000

      I exported the template and discovered the following byte sequence:

       

      I removed that character and imported the fixed template:

      $ diff -u zbx_export_templates_exported.xml  zbx_export_templates_fixed.xml

      This solved the problem instantly.
