You can solve that for the moment here:
if you’re using wordpress’ default single-template
copy views/single.php
to your local theme /wp-content/themes/{your-theme}/events/single.php and change Line 13
from
if(strtotime(tribe_get_end_date(get_the_ID(), false, 'Y-m-d G:i') . get_option('gmt_offset') ) <= time())
to
if(strtotime(tribe_get_end_date(get_the_ID(), false, 'Y-m-d G:i') + (get_option('gmt_offset') * 60) ) <= time())
if you’re using the ecp-buildin template copy that instead of the single.php
Best,
Rico
