My guess is it is your 'Partial Structure Display' settings changing.
These are saved with the views so can be different for each one.
These will affect the dimension because the dimensions are specific for each PSD - i.e. they only show on the PSD that was active when the dimension was placed.
Or it could possibly be the Renovation Filters.
These too are saved with each view so as you change views in the View Map you may be invoking different settings.
