Anomaly with Expenses

I have several users that when they add an expense and enter a budgeted instead of a price/unit and budgeted units, the next expense they enter comes in with the same budgeted cost even if the expense is being created on a different activity. This is not happening for all users. The users are on stand alone installs and are either running 16.1 or 16.2. Has anyone else seen this anomaly? Is there a setting that I am missing?

Thank you,

Erin
