Inconsistent pedal mod amounts

First, as others have requested, I wish the maximum amounts for modulations on the panel were larger, specifically in the VCF and VCA section. To get more range, I’m trying to extend the modulation amounts with an expression pedal, but this yields inconsistent results:

Pedal routed to VCA LFO 1 gives me a larger range than what the LFO 1 slider has access to (this is the behavior I hoped for) but PED routed to VCF ENV or VCF LFO 1 does not: the maximum remains the same.
