Unable to edit eps files

Hi there, 

This has been an issue I have been experiencing for a long time. I'm currently on CorelDraw2020 subscription. Each time I purchase an Scalable Vector (.eps) from stock, I'm unable to edit the file. I have done everything under the sun but still no joy. My colleagues in the industry using illustrator has no issues opening the same file that I am unable to open in CorelDraw.  

Any solutions? 

Thank you.
