@ Laird, you would probably have to correct this for the already imported items in Settings - LMM Meeting- Schedule tab, where you would have to pick the correct item from the dropdown in the first column (it is a dropdown) for that particular meeting item. So do that first. (Find the Memorial invitation part(s) and you'll see they are probably connected to First Call or Return Visit)
If that doesn't work, deleting those weeks (same tab, top box, delete week by week) and reimporting the workbook may help.
If that still doesn't work, you may have to actually delete the items from the database (deleting them via the UI just flips the Active switch in the database from 1 to 0.
