Cannot edit caption from stock company

Hi,
I cannot edit the caption right under a photo (not the tags), provided by a stock photo company. 
Somebody obviously already moved the picture to the correct spot.

The photo is the main picture of the series "The fall guy", episode "Devil's Island" Season 3 episode 1. Aired in September 1987.

This is absolutely correct, I am watching the episode and I confirm it.

However, right under the photo, contributors cannot Edit what the stock company wrote:
"The Bionic Woman" Lee Majors, Lindsay Wagner circa 1975

This photo is really of Lee Majors and Lindsay Wagner, but it's not from the series "The Bionic Woman" (1974-1978), it's from "The Fall Guy" and certainly not "circa 1975". Photo was taken 12 years later, in 1987.

Can someone correct the captions please, as I can't, thanks!
