Width of new Table Mapobject

Hello,

i'm using a table on my maps as of the beginning of our PRTG installation. Scaling was working properly since then. But now the mapobject scales itself down to the minimum size. it should have the width and height of the red frame in the example picture ( https://i.imgur.com/HPJJ5h5.png )

Where can i edit the mapobject itself?

the code of the custom mapobject is:

<!--Custom Map Objects: Alarms an Warnings only -->

<div class="map_object map_table" id="<@itemid>" objectid="<@objectid>" subid="<@subid>" style="overflow:visible;<#mapobject type="coordinates" subid="<@subid>" mode="<@editmode>">">
  <#mapobject type="objectgrip" mode="<@editmode>">
  <#mapobject type="htmlbefore" subid="<@subid>">
  <#checkobjecttype objecttype="probenode,group,device" nicemessage="true" id="<@objectid>">
  <div class="maptablecontainer" style="overflow:hidden;font-size:24px">
    <#lang key="html.dashboard.alarms" default="Alarms" var="alarms">
    <#lang key="html.dashboard.warnings" default="Warnings" var="warnings">
    <#objectstatus name="downsens" id="0" show="htmllink" var="alarmcount">
    <#objectstatus name="warnsens" id="0" show="htmllink" var="warningcount">
    <b><#inserthtml html="@alarmcount @alarms, @warningcount @warnings" varexpand="html"></b>
    <#table tableid="dashalarmtable"
      content="sensors"
      id="<@objectid>"
      columns="downtimesince,type,device,sensor"
      count="20"
      sortby="downtimesince"
      links="false"
      sortable="false"
      infoheader="false"
      filter_tags="@tag(<@tagfilterstring>)"
      filter_status="5"
      filter_status="4"
	  >
  </div>
  <#mapobject type="htmlafter" subid="<@subid>">
</div>
