VUmeter Bands in BOOMBOX Style , only two led in red ( not 3 as normal)

[IU4ALH]

Good morning.
I wanted to report a small inconsistency in the display of the Vumeter bands.
In practice the Vumeter correctly shows the last three bands (maximum signal) three red LEDs, but if the BOOMBOX function is activated then only two LEDs are displayed for the red bands. I asked you if it was possible to fix this, and at the same time add more red LEDs, for example four. Finally, always if possible, add another color for the lower signals, that is for example out of 10 LEDs (bands) the first three (low signal) yellow, the further three (medium signal) green, the last 4 (strong signal) red.
Thanks from Antonino IU4ALH
