Opening pdf-files in CorelDRAW after they have been edited in Adobe Acrobat Pro

Hi everyone.
I have a question regarding opening pdf-files in CorelDRAW after they have been edited in Adobe Acrobat Pro.

What I do is to edit pdf-file in Adobe Acrobat Pro, save it (still pdf) and than try to open it in CorelDRAW, which says: "Invalid file format" :(
I tried to print the edited file as pdf (kind of secondary pdf-file) and open it in CorelDRAW. It works! But theissue is that text are being konverted into curves, yet I chose tick box for Text.
Does anybody have same experience and found a solution? I use CorelDraw 2019 (64-bit) for Windows.
Best regards,
Ksenia
