Season Maintenance bug?

Hi everyone - 

We have some recent reports since from our Box Office users that pricing seems to have changed for the first price type and first zone when work is being done on multiple performances in Season Maintenance. For example, the user will select multiple performances in Season Maintenance/Manager, move to the Pricing tab to update prices on the pricing grid, update prices not for the top (base) price type or first zone, but will, upon save, see those prices having changed. I could see this being unintentional user error, as that is the cell selected when the screen is loaded, but we want to do due diligence to investigate! This sound familiar to anyone?

Thanks,
Frannie
