this xelatex template's abstract section automatically add thesis title at top, here's the template live demo in overleaf: https://www.overleaf.com/read/jkrpnmrnmqwz
i've looked around for hours and still cannot solve it, it seems it's not a common situation in english template. the abstract page is not even used, so i guess some other packages include it? i've also checked the abstract package documentation pdf, no help.
I suggest to try what follows. Go to your project and select the class file oucthesis.cls
.
Scroll down to line 252:
Now comment line 252 with a %
character at the beginning of the line:
% \fontsize{16\bp@}{26.67\bp@}\sffamily\@title
By the way, you can comment all the three lines from 251 to 253.
This should make it, otherwise please comment below my answer!
