All Product labels are changed to Sale labels

Hi,
I have added a custom label i.e. Buy 2 Get 1 as a custom attribute label , and for another product I have set it as out of stock ,

Both labels are reflected properly for guest users but when I logged in all my labels are changed to sale labels, when I check it in via inspecting the page :

Before log in :
<div class=”product-labels labels-rounded-sm”><span class=”out-of-stock product-label”>Sold out</span></div>

After log in :
<div class=”product-labels labels-rounded-sm”><span class=”onsale product-label”>Sale!</span></div>
