strange behavior on product preview image

That look like your theme override the plugin text. You should investigate more in your theme, but for quick fix, you may add this style to your theme:

.product_actions_tip.__text.add + .product_actions_tip.__text.added,
.product_actions_tip.__text.add ~ svg {
    display: none;
}
