Maybe I'm confused on what you have going on exactly? I'm not so sure using those pigtails is the best solution, as a keystone plate with HDMI couplers is what I would have used. What I'm trying to say is you shouldn't have to use a repeater.
The pigtails don't even say which version of HDMI they support, and look a little questionable

these are HDMI 2.1 and what I would use.
