I think there ist a mistake in line 164 of class.tx_t3sjslidernews_pi1.php
The OWN_MARKER_TWO is not rendered in the template.
I changed (Line 164)
$this->extConf['ownMarker_1'] = substr($this->extConf['ownMarker_1'], 8);
$this->extConf['ownMarker_2'] = substr($this->extConf['ownMarker_2'], 8);
The OWN_MARKER_TWO is rendered fine now. Is this correct?
