Ghosting using RF adapter and EF lens

[cpmyork]

Was outside in bright sun, high contrast scene using an R5 with the Canon adapter and a 24-105 EF lens.  Notice a lots of flare and ghosting in the whites.  Doesn't show with the same lens on the 5D at the same settings.  Anyone else noticed this affect or better still, have a solution short of buying all new RF lens? Thanks

I had the folks at the shop take shots with it and they suggested I send in back for service as they experienced the same issue.  I had hoped it was operator error but doesn't seem to be. Thanks all for helping me think this thru
