H1B extension of stay approved but I94 not backdated

My I94 was shortened due to my passport expiry in 2023. After overstaying for a year, my employer filed for H1B extension of stay (NPT) which got approved.

But the I94 record on the new I797 was not backdated and hence does not cover the gap in my I94 record.

How will this issue affect my future international travel and H1B visa renewals?
Can my firm or I take any steps to rectify the gap in my I94 record?

Normally, the rule is that if the extension was approved, you are fine.

My Opinion is that you should write about this gap period on DS160 whenever you fill it for visa stamping.
