Hi TS,
To remove the date and location in module on homepage, you can open the file: ROOT/templates/ja_teline_v/html/layouts/joomla/content/intro/event.php
Find and remove this snippet of code (at approx line 40):
<li>
<i class="fa fa-calendar-o"></i>
<span itemprop="startDate"><?php echo JHtml::_('date', $item->params->get('ctm_start',''), 'DATE_FORMAT_LC3'); ?></span>
<?php if($item->params->get('ctm_end') != ''): ?>
-
<span itemprop="endDate"><?php echo JHtml::_('date', $item->params->get('ctm_end',''), 'DATE_FORMAT_LC3'); ?></span>
<?php endif; ?>
</li>
<li itemprop="location">
<i class="fa fa-building"></i><?php echo $item->params->get('ctm_venue',''); ?>
</li>

For the date / location in detailed Event article page, you can open the file: ROOT/templates/ja_teline_v/html/layouts/joomla/content/item/event.php
And remove code which renders date as you wish: http://prntscr.com/ceqmob
