Hi,
I could not login to the back-end to check, but from the source code it looks like it is printed via the advanced title field. I recommend checking that first, it should contain something like this
<span class="searchptitle">product</span>
If nothing like that is in there, then it might be included in the price field(?). In that case, this simple custom CSS will hide it:
.asp_r .searchptitle {
display: none !important;
}
