Error on preview when inserting a brief on generic

Hello,

Does anyone have any idea why am I getting this error when I preview the page after inserting inline template which is a brief. I do not get any errors to save the item but on preview this is what comes up:

Error processing inline link Problem while processing inline link for item 1-101-15603: The processing instruction target matching “[xX][mM][lL]” is not allowed. See the replacement body in the console log. The attributes on the affected link were: class=“rx_ephox_inlinevariant”,contenteditable=“false”,inlinetype=“rxvariant”,rxinlineslot=“105”,style=" display: inline;",sys_dependentid=“1036”,sys_dependentvariantid=“501”,sys_folderid=“717”,sys_relationshipid=“43803”,sys_siteid=“305”,unselectable=“on"Original content:<div class=“rxbodyfield”><p>Test brief</p><div class=“rx_ephox_inlinevariant” contenteditable=“false” inlinetype=“rxvariant” rxinlineslot=“105” style=” display: inline;" sys_dependentid=“1036” sys_dependentvariantid=“501” sys_folderid=“717” sys_relationshipid=“43803” sys_siteid=“305” unselectable=“on”><p contenteditable=“false” unselectable=“on”>this is just a test</p></div></div>
