LR not sorting by capture time properly on Web version

Hi folks,

I use Lightroom CC and Lightroom Web to host an image archive for my company. The higer-ups at my company tend to use the web version while I use CC due to the increased functionality. 

I am sorting by capture date from earliest to latest, and on the CC version, it shows correctly. However. on the web version, it is insanely out of order.

It starts with a few photos from 1979, then goes to 1974, then to 1976, etc. etc. - it is all over the place. how can I fix this?
