I can open a PDF with layers but it creates hundreds of them.
Instead of having ten layers there are hundreds of them with small groups of objects in those same layer names over and over.
The only way I can think to fix it is to make 10 different PDFs with each of the 10 layers and bring them in one at a time.

Can you share a sample PDF file that has this problem when you import it into CorelDRAW?
Don't see a file upload. But here is a print screen link:
The import works but why are all the layers broken up into many layers of the same name? Some have just one or two lines/objects in them. ???
Without a PDF file to try, I have no way to try importing the file myself to see if I get the same result.
If the file isn't too big, you can insert it into your post. - Insert>Insert image/video/file. You might need to put it into a ZIP archive in order to upload it; I don't know if the system will allow PDF files.
Or, you could provide a link to where you have shared the file on-line (e.g., Google Drive).

Here is a small part of the PDF. In Acrobat there are 3 layers. One I merged to delete stuff and even though there is nothing in it CorelDraw adds many layers for it and the other 2 also turn into many layers.
I tried importing it into CorelDRAW 2018.
The result:
6 layers named "AI-SV16-1F-ARCH|A-BLDG-FIXT" with objects in them
3 layers named "AI-SV16-1F-ARCH|A-BLDG-STRS" with objects in them
587 layers named ZZ_DeletedLayers with no objects in them.
