Incorrect employer name on H4 Visa

[H1B for skilled workder]

I worked for Employer A till april 2018 and got two approved I787 from different employers  (Employer B, employer C).

I joined employer B and booked VISA appointment for my spouse. She got her visa stamped incorrectly with employer C. 

Please let me know if she can travel with my employerB approved I797 copy without correcting her VISA. If it needs to be corrected before travel please help me with the process of correcting it. She is travelling first time to United States and dont want her to be panic at port of entry

The H4 is not tied to any employer. An employer name on the H4 is irrelevant.
