Hello [userlink]JJTTBB[/userlink],
This is not a bug. SMath checks that the unit you assign in the rightmost placeholder is consistent with the units given in the left hand side.
If your intent is just to display a result, or you want to make dimensionless calculations and assign manually the dimensions on the results, right click on the region and select "Ignore units", then this feature will be ignored

Otherwise you have to assign the units in the LHS, and eventually adjust the result (results are given in base units)
