Issue with List output - same records are repeating

[govind_parmar]

hi UI5 Experts,

I am having issues with repetitive data in my UI on the list , although the backend data seems to be okay.

Below is my code: 

Manifest:

    "dataSources": {

      "polService": {

        "uri": "sap/opu/odata/SAP/*********/",

        "type": "OData",

        "settings": {

          "annotations": [],

          "localUri": "localService/metadata.xml",

          "odataVersion": "2.0"

        }

      }  

XML View:

The view has an input which is being used as a filter condition in the backend api.

Input value is '12344' taken in this example:

<Input id="input2" 

value="{/InputValue1}" 

valueLiveUpdate="true" 

width="200px" enabled="{/enabled}" 

liveChange=".onLiveChange" />

<Panel backgroundDesign="Solid">

<List id="polServicetab"

headerText="{i18n>BillingAccountPoliciesTitle}"

class="sapUiResponsiveMargin"

width="auto"

items="{polService>/PolicyDetailSet}" >

<items>

<ObjectListItem id="ObjectListItem1"  title="{polService>PolicyNo} X {polService>BillType}"

number="{

parts: [

'polService>PremiumAmt',

'view>/currency'

],

type: 'sap.ui.model.type.Currency',

formatOptions: { showMeasure: false}

}"

numberUnit="{view>/currency}"

/>

</items>

</List>

</Panel>

Controller:

onLiveChange: function (oEvent) {

var aFilters = [];

var sfilterVal = oEvent.getParameter("value");

if (sfilterVal) {

aFilters.push(new sap.ui.model.Filter("BillingAccountNumber", sap.ui.model.FilterOperator.EQ, sfilterVal));

}

const oList = this.byId("polServicetab");

const oBinding = oList.getBinding("items");               

oBinding.filter(aFilters);  

}

From back end service polService>/PolicyDetailSet('12344') returns me 8 unique entries but for some reason the last entry is being repeated 8 times as shown below:

Please can you let me know 8 entries are being repeated, I could see the PolicyDetailSet('12344')  is being repeated in the keys , not sure why.

Also is there a better design based on the above requirements.

Thanks.
