sorry I thought that was the gallery
in the replay.rpy file find this section
for i in range(start, end + 1):
if renpy.seen_label(Replay_items[i].replay):
hbox:
spacing maxthumbx - 20
xalign 0.5
yalign 0.1
text Replay_items[i].name # make the same changes as before but to this line add the colon and the outline command below it
