Excel Exports format incorrectly in LBI

It has always been a challenge to get some of our more complex reports to export with correct EXCEL formatting in LBI but now newly published reports have some real issues with the columns when exported. It appears that the exported report totally ignores the columns in the published Crystal report. These same reports export beautifully when directly exported from Crystal to Excel outside of LBI. I reached out to a peer who is also a consultant and he is having the same problem. Reports that were published several weeks ago do not have the issue, it is only the newer reports so we are stumped. We have tried republishing the reports under different numbers, reformatting the Crystal reports with every suggestion that was provided and have not had any success.
