After a recent update my Fusion no longer generated T? M6 in the post processor file

I don't think I have changed anything. I checked my tools and they are not set for manual change. I have the some post processor and machine definition as I did a few weeks ago. The post processor has Use M6 checked:

I am using the full version (educational) of fusion -- not the hobbyist version.

The code that is generated looks like:

G90 G94 G40 G49 G17
G21

(MANUAL TOOL CHANGE TO T11)

Note that the comments about the manual tool change are there rather than the T? M6.

Any ideas on something I might be doing wrong as opposed to something broken in Fusion?
