Retro Access cables scrambled signal on PVM M2U20

I'm running the 15 kHz SCART cable through my shinybow SCART matrix switcher.

Admittedly the first time I screwed up and started with the HDMI ini file, after realizing my blunder I blamed the scrambled signal on the wrong ini. So I FTPed into my Mister from the HDTV and changed the default ini file to analog RGB ini yet the scrambled signal persists.

What am I doing wrong? Does switching the defaults around confuse the device? The only thing I didn't try is manually setting the ini using the script from the OSD but I didn't think I would need that. I figured so long as I make sure HDMI and DVI are set to 0 and composite sync is set to 1 it should work?

Here are both of my ini files: MiSTer_alt_2 is HDMI (was the default before I switched file names), MiSTer.ini is the new 15 kHz RGB one.

The scart selector set-up I'm using connects into a M2U20 via SCART to BNC cable with built-in sync stripper.

EDIT: It was my sync stripper inside of my SCART to BNC lead that's the culprit. Luckily I got another SCART to BNC lead WITHOUT the sync stripper and that thing works like a dream.

2nd EDIT: Didn't mean to create a second post. Just wanted to update first, my apologies?
