I searched for an award itin from Europe to HNL. One of the options is a KL flight to AMS, then KL to SFO, then DL1151 to HNL. If I hover my mouse of the DL 1151 flight I get a pop-up with some info on DL 1151. However, if I click on the link I get a pop-up with info on KL 1151 (AMS-OSL) instead of DL1151 (SFO-HNL).
The same happens for other options. AF to CDG, then AF to LAX then DL2365 to HNL. I click on DL2365 and it brings up info on AF2365 (BLL-CDG).
