That gas block has a line engraved into it underneath the gas tube to add in alignment, so take a pencil and strike a line bisecting the gas port over the shoulder. Take gb and remove the set screw underneath the blocks gas port, slide it on upside down on the barrel and line up that set screw hole to the gb port and take note of how far off the barrel shoulder that perfect alignment takes place. Rotate gb and align the pencil mark to the engraved mark with the proper gap from the shoulder and tighten.
It sure looks like you have a decent amount of gas leaking from your block to the barrel and the gas tube and that is likely an issue. Odin has good customer service you may want to reach out to them and discuss it with them and sending them pictures would be good, if you can measure the gb journal and the opening of the gb that may shed some light. My tunable block didn't spue out gas as your pictures show. Some guys use loc-tite to bed their blocks and gas tubes but one needs to be careful doing that as you don't want it to get in your port.
eta; be careful installing the locking long setscrew for adjusting the gas as I've heard others mentioned they noticed when they screwed it down to lock the inner screw that it actually turned the inner screw as well changing the gas setting.
