With reference to LCS issue 921873:

When switching from a personalized/custom view to the ‘Standard view’ in the trade agreements form, all trade agreements are shown instead of the one from the particular vendor or customer account.

The behavior is confusing for users, as well as causing great loss of time to exit and re-enter the form to have the needed information displayed, since data is reviewed multiple times per day/per user. 

Users would greatly benefit if a change would be introduced as such to accommodate the current limitation, reduced efficiency and user sentiment would be avoided and would come in aid with the daily user experience.
