Macro Behavioral Issue

I assigned Macro 2 to detune on both OSC A and B, but on A the modulation range is one-directional (like an ENV) while on B it's both (like an LFO)

I assigned Macro 1 to do the same and both were one-directional.

Am I doing something wrong or does this need to be fixed? I can include larger screenshots if necessary.

You can shift-alt-click (or use the matrix) to toggle uni/bidirectional.
The assignment on OSC A was due to the value not being at 50% when you made the mod assign.
