22:41:31 koha_1       | An element could not be located on the page using the given search parameters: //div[@class="main container-fluid"]//a[contains(@href, "/admin/branches.pl?op=add_form&branchcode=UT_BC")],xpath at /kohadevbox/koha/t/lib/Selenium.pm line 174.

The screenshot was obvious, the UT_BC was not on the first page.
There was a total of 33 libraries at this point, which is not expected,
maybe data not deleted from previous selenium tests.
