I have a list on which OOB approval workflow is running. In the list there is a column which shows the workflow status such as "Pending", "In Progress", "Completed" etc.
Today I found out that the column is showing blank. It was previously showing "Completed" or "Pending" (depending on circumstances) for each item but now it is showing nothing and just blank. Why did it happen? And this is not the first time it has happened and last time it happened was more than 2, 3 months ago.
Any reason why this is happening?
