Hello @Jose_Jabe - welcome back to the forum!
It’s hard to tell from your description what you’re seeing-- could you include a screenshot?
This picture below is from the OpenEMR v6.0.0 (4) demo.
When you create a new encounter you then add clinical forms to it from the menu at the top center of the encounter form (oval).
When vitals have been added they will appear in the encounter form (rectangle lower left). Typically only one set of vitals is put in an encounter but it isn’t unusual to enter more than one. So if you want to add another set you may by selecting it from the ‘Clinical’ menu (arrow) and entering the data into the form.
Do let me know if I didn’t understand what you are asking.
