Bug - Growth Density
 

In Power Profiles
DENSITY INCREASE
Rather than increasing your size, you increase only your
mass, becoming more dense, and therefore stronger and
tougher, without changing size. This removes the following
modifiers from Growth: active defenses (Dodge and
Parry), Intimidation checks, and size rank. Only Strength,
Stamina, and mass ranks increase. Speed rank actually decreases:
–1 to speed per 4 ranks.
Gamemasters should enforce the significant limitations of
the character’s increased mass; a character with 10 ranks
of Density Increase weighs 100 tons! Few, if any, conventional
structures will support the character’s weight.
Density Increase: Growth, Does Not Change Size (+0
modifier) • 2 points per rank

In Hero Lab the Active Defences are still being reduced and doesn't adjust speed ranks.

I have been trying to get that to work. I have everything working except changing speed rank - that's why I asked the question on how to change the speed rank for the size change only with no reply. I'm beginning to think that Wolflair has forsaken the M&M forum totally. I hope you have better luck then I have.
