column headers will not render, columns cant be resized in IG report, APEX v. 19

I develop APEX reports that are accessed via EBS [function on menu]. Most reports work just fine, but one report the column headers dont render and the columns themselves cannot be resized.

The report summarize misc transactions for stock in inventory by year. I created a view in the EBS database that summarizes the transactions and in apex i just retrieve the data.

I tried to do the actual summarization in APEX itself, and that didnt resolve the issue.

When i run the report in APEX design tool, everything works fine regardless of which way i design the report.

Any ideas on how to resolve this? obviously i have not run into this before...
