Another interesting observation on this set of PSE fang 350 cams is that it has two sets of single ended cable lobes. One set it much less taught than the current setting. Therefore I'm assuming there are two main string sizes for this set up. This is the 350fps 175LB draw set up. I suspect there is a lower power setting of perhaps 150LB but because there is only one set of main string lobes you'd need a different size main string.

Can you post a picture of that?
I definitely don't see that on my Fang 350. Also, the Fang 350 is listed as a 155lb draw. Maybe these bows aren't as similar as you think?

OK, took a picture. The system doesn't work like I thought it did. It uses the same lobe but has two spindle holes with two different cable guides. That's what I'd seen, two seperate cable guides. Now, looking at this I'm assuming you strip the cables off, change the cam into the other spindle hole and the cables go around the second guide. This must be how it works. It's definitely a two way system, you can set it up two ways. One system looks to be marked 2 and the other 5.

I'm not seeing the "second cable guide" in your picture. I think if you cock the bow and take another look it will be clear that all parts of your cam are in use.
Also, your cams are different from the Fang 350. Here are some pics of my cams, circa 2016 PSE Fang 350.
