sorry i am not able to share url because its a website hosted on my local machine(i usally do a test with this local website before pushing any changes to production website ). My production website works absolutely fine (runs on demo 9)but i like to switch my current site demo 9 to demo 14. But i found these bugs on demo 14 menu and more buttons. Any way i was able to fix the issue with some changes in wp cutomize>custom css. Now everything works fine.If you really want see the bug just look into your demo website https://wplms.io/demos/demo14/ by login with any user account.i Saw some other users experience same issue with demo14 website. I am sharing tweaks i made on custom css.
.minimal #buddypress div.item-list-tabs ul{background:#fff;border-radius:5px;overflow:hidden;}
above code is changed to
.minimal #buddypress div.item-list-tabs ul{background:#fff;border-radius:5px;overflow:show;}
and also adding
.flexMenu-popup{
width:180px !important;
}
to end of the custom css
