Here's a screen-grab of the relevant page I found in Shimano's manual for the
Rear Derailleur: Shimano CUES RD-U6020 (10 Speed) on my Diverge -

I'll relocate that cable into the groove, see what happens....
When I received my Tarmac (same vendor) near the end of the 2024 biking season I wondered why I was having some 'issues' over the FDR performing as I'd expected. Taking things further (as is my preference, and as I'd not dealt with a 'local' dealer) I came to learn that its little 'support screw' (virtually hidden in the DR mech) needed to be tightened against the backer plate bonded to the CF seat tube, otherwise the DR would twist slightly under cable tension. Don't recall if that came via a tip here on the BF forum (I'd just recently joined) or my searching through Shimano's maintenance files on line. Tightening that little screw fixed things virtually instantly.
most of the time, the shift cables are attached at the factory, and should be close to adjusted before crating too.
maybe they leave the rear der. off the bike now, to limit shipping damage...?
can you imagine the fight it took to get that cable clamped in place like it was?
i imagine it raised a bit of a sweat, and required pre-bending, to achieve the wrong thing.
the rounded outer edges of "the slot" become the cable pull point, not the clamp plate... it SHOULD reduce the chance of flexing/wear/breakage at the plate to zero... that portion of cable sees high stress anyway, due to over-clamping of the cables. "It can still move! i'll just add another half turn or two....."... mush.. fray... break, eventually........." i've seen it too many times.
