Online I-94 does not reflect the latest I-94 received with approved I-797? Which I-94 is valid?

I entered USA in mid 2017 (on H1B). The I-94 I received at that time had an admit until date of 08/28/2018. However, I applied for a H1B transfer in late 2017 and got an approved I-797 with a new I-94. The new I-94 I-94 says "VALID FROM 11/20/2017 UNTIL 11/29/2020". Also, I recently applied for a new passport since my old passport (with a valid H1B stamp) was going to expire.

So when does my I-94 expire? When I look up online on the DHS website, it still shows the old I-94 with admit until date of 08/28/2018. 

Thanks.

Your latest I94 is controlling. Stop looking for problems where there are none. If you want ask the lawyer for the employer.
