This seems a bug in CB templates, for a new forms formatting affecting users-lists and lost password forms.
So please try this:
Open a web-page on the lost password form, and check how it goes with the different checkboxes checked.
Then:
open template.css in your CB template:
components/com_comprofiler/plugin/templates/YOURs/template.css
search for this line:
[code:1]form.cb_form { width: 100%; float: left; margin: 0px; padding: 0px; border-width: 0px; }^M
[/code:1]
and comment out the float:
[code:1]form.cb_form { width: 100%; /*float: left;*/ margin: 0px; padding: 0px; border-width: 0px; }^M
[/code:1]
Open a new "lost password" page side by side with the previous, RELOAD page to clear your browser cache, and check that the lost password form still looks same.
Then go to users-list which had problem, RELOAD page, and see if ok.
Please report back your finding here asap, so we can quick-fix it.
