can`t locate angle on bow slide ruler.

[Harbinger1]

I can`t locate angle on bow ruler. I do get the conversion table with M and KM conversions but I am missing the top part which has the Angle on Bow conversion info that I need.
Stoianm link below will show what I am missing, We both have DarkWraith`s NewUI_TDC_6_9_0_Real_Navigation and in his demo ( link included below ) he is able to access the Angle on Bow Ruler but I can`t.

I was sent this link by Harmsway; "Yes you need the RAOFB mod noted below the YouTube video. See Ui-Boat V5.xx thread on this mod. I believe you can also get RAOF with an add-on to the Multiple UIs for SH5 with TDC and Automation mod." MY problem with this Mod is that it includes a new UI interface and is not compatible with my installed DarthWraith UI which I like and want to keep
