New column added to Dataflow not displaying in Dataset

I think I have a similar issue and found the root cause.  In my scenario, I created a custom column in Decimal format.  Preview data in dataflow looks good, but the new column does not show up in the entity/table after refresh (as confirmed by connecting to this Dataflow table from PBI Desktop).  I had this issue a couple months back, and could not confirm why it was happening.  Then today I looked into the Advanced Editor (M Query) and found that the final "in" statement points to not the last query step as usual, but points to the step before I made the latest custom column.  Example of the M Query having the issue.  I assume this issue will be fixed when I adjust the M Query manually, not sure why it occurred in the first place.
