Combobox show incorrect Text o after a few selections and deselections

[Nelson]

Hi there, i have an issue with sfcombobox. 
When a value is selected and deselected a few times the combobox start to shows a wrong Text or DisplayMemberPath. First it shows a Text diferent from the SelectedItem and after a couple trys it modifies another combobox showed Text.
In this particular case the selected value in DeliveryDepartmentPicker changes the FiscalDepartmentPicker Text, but the selected value is always correct . Its like if the Text doesnt change correctly with the SelectedItem.

(The property Text wasnt needed at first, we were using DisplayMemberPath only, but it was implemented because the fields doesnt actualize properly after clearing everithing from viewmodel)

In the attached file is visible how a value is selected and ahother is showed
Thanks for your help

Hi. I found a solution but im still dont know why it doesnt work in a normal way.
In the image u can see the result var that should be the selected item, but is an object with the correct id and the wrong name (the name is from a previous selection)
So in the last line i search the selecteditem by the Id from the local db .
