Looker 26.22 will roll out to Looker (original) instances on the following schedule:

Table row group subtotals are now displayed only for sum and count measures.

For other measure types (such as averages and count distinct ) and table calculations, subtotals are now left blank rather than displaying an inaccurate summed value.

An issue has been fixed where custom visualization tiles were truncated in dashboard PDF exports when the Expand tables to show all rows option was enabled.

This feature now performs as expected.
