Custom text before price

-- HikaShop version -- : 6.5.0
-- Joomla version -- : 6.1.1

Hi!

Before the price i added a custom text "Our price" in the view file.
The thing is that i have characteristics in the products and when you select a characteristic from the dropdown, that texts disappears.
How can i have it there for all characteristic prices as well?

Thank you
