Incorrect Chart Data in Interactive Service Hub

Hi,

I have a custom dashboard in Interactive Service Hub with two charts as shown below .

First one is a simple chart 'Cases by Priority'. Second one shows all Cases with associated orders that have certain custom status reason. I have implemented this using exporting the chart and editing the fetchxml & importing back again. But we also see a column with blank values in the second chart.

To remove the blank column I removed the link-type=outer in the fetchxml of the chart and this is how my fetchxml looks now :

<entity name="incident">
  <link-entity name="salesorder" from="salesorderid" to="dow_order" link-type="outer">
  <attribute groupby="true" alias="_CRMAutoGen_groupby_column_Num_0" name="statuscode" />
    <filter type="and">
    <condition attribute="statuscode" operator="in">
     <value>179920004</value>
     <value>179920003</value>
     <value>179920005</value>
    </condition></filter>
  </link-entity>
<attribute alias="_CRMAutoGen_aggregate_column_Num_0" name="title" aggregate="count" />
</entity>

But after removing link-type="outer" & importing chart, this is how my charts looks like :

As you can see black column in second chart is gone, but data in my first chart is incorrect.

Any idea what would be causing this?

Thanks,

Pradeep
