I see two rather ‘quick’ ways of doing this: either you hide what appears to be the page title by css, or you edit the page template accordingly. Both should be done in a child theme.
Hiding the title with a few lines of css would probably be the quicker, but also a bit dirtier way to do this. For example:
.entry-title {
display: none;
}
You’ll find an introduction to child themes here at wordpress.org.
