Importing PDF into Corel... strange behavior

I wonder if anyone else has noticed this.

I have created a PDF from Word and From Excel... doesn't matter which. From there, I import the PDF inot my Corel document. It looks fine but all elements are loose, not grouped.

When I group the items created by the import, un-select and then re-select or re-size... some new is added to the group and it is either taller or shorter than the actual content. When I break the group apart, I can select the added element which is invisible. I can literally delete the extra item and regroup and it starts all over again.

There isn't a performance issue here although it is annoying when trying to align.

I just wonder if anyone else has noticed this. See the example below. The latter is the grouped items.
