Do you have an additional copy of default/hud/default.txt in your override folder that might be being used instead?
Your default.txt file should look like this for that section:
Code:
//Toolbar position 0,0, (1 to anchor to minimap or 0 for no anchor)
//Default toolbars overlap and enabled via tabs/keys
//ToolbarsPos=0,0,1
//ForceAllToolbarsOn=FALSE
//HelmToolbarOffset=0,0
//DiveToolbarOffset=0,0
//SensorToolbarOffset=0,0
//Force all toolbars on in bottom horizontal row
ToolbarsPos=0,0,0
ForceAllToolbarsOn=TRUE
HelmToolbarOffset=331,-346
DiveToolbarOffset=640,-346
SensorToolbarOffset=953,-346
//Force all toolbars on in right vertical stack, anchored to mini-map
//ToolbarsPos=0,0,1
//ForceAllToolbarsOn=TRUE
//HelmToolbarOffset=0,0
//DiveToolbarOffset=0,71
//SensorToolbarOffset=0,142
