Change the word 'Quantity' in store

Hello, 

I am trying to change the word 'quantity' on my service items in my store. However after 15-20 mins the code below changes to everything to Quantity (1 Ticket) in my store.  Any assistance would be appreciated

code: 

#item-656fd3d8dad09a7a18b6c37f .quantity-label { visibility: hidden; } .quantity-label:before { visibility: visible; content:
"Quantity (4 Tickets)"; display: block; }
#item-656fca47263fd234be06c04e
.quantity-label { visibility: hidden; } .quantity-label:before { visibility: visible; content:
"Quantity (1 Ticket)"; display: block; }
#item-65b00151b67fcf78a112eda8
.quantity-label { visibility: hidden; } .quantity-label:before { visibility: visible; content:
"Quantity (4 Tickets)"; display: block; }
#item-65a9d3f860f1595519aea2c2
.quantity-label { visibility: hidden; } .quantity-label:before { visibility: visible; content:
"Quantity (1 Ticket)"; display: block; }

Thanks for your reply. This does change the label Quantity, but it does it for all the items in my store. Some items have 1 quantity and some have 4. 
I added the product ID before .quantity-label but it did not work
