I have found this to be true in the only ones I have really tested so far -- Sales Order notes.  I printed Evo notes for the customer, saving the settings.  Then I changed the Evo notes to print  different customer notes and saved the new setting.  Everything seemed to be working, but the previous notes printed along with the newly selected ones. When I went back into SO-B and ran the print again, the old settings were still showing.
Hopefully when the new T7 versions of SO and PO are completed this problem will disappear.  
In the meantime, I will probably do without Evo notes in my live company.
