Hi all, I am in need of some 4x4x4 help.
I browsed a lot of websites, searched the forum but I cannot find a solution for the attached case.
My cube is currently just like this, with two mirrored "yellow-orange, yellow- red dedges" and I cannot fix it.
Details: this is only my 3rd solve, I am using a simple method to line up edges and insert them "intuitive 3x3x3 F2L" style.
I already noticed that I had two wrong edges but I expected that this would end up in one of the parities I found on the web.
This drawing from Dan Harris' site looks like it but I really need to swap only two edges, not two "dedges". Aplying Dan's algo switches four pieces, resulting in the exact same issue.
Dan's image:

r2 R2' U2 r2 R2' u2 r2 R2' u2 (swaps UF with UB)
