pdf export no longer works correctly

I am able to export to pdf a complex type setting WordPerfect file in version X7.

In the 2021 version of WordPerfect it does not even export (publish) to the pdf. I requested help from Corel and uploaded the file and received a garbage response. Please fix the pdf export (Publish to pdf). Otherwise, the WordPerfect software is useless to me and I will not be upgrading.
