Angular New Manager Product unsubscribe

Hello,

in the actual Angular Portal Version 9.2 (from GitHub) is a cool new feature that when i create a request for a Identity to assign a "New Manager" a ShoppingCardItem is created and in dies Request i can select witch Produkt should be unsubscribed.

but per default all products are selected. 

how can i change this that per default is nothing selected. 

Angular get this over API call .../portal/cartitem and in Response this ExtendedData wich Value:true are visible

"ExtendedData": {
"CheckResults": [
null
],
"ItemData": [
{
"UiText": "Wählen Sie den neuen Manager und alle Berechtigungen aus, die zum Stichtag entfernt werden sollen, wenn diese Bestellung genehmigt wird."
}
],
"Parameters": {
"DialogParameter": [
[]
],
"ComponentParameter": [
[
{
"Value": {
"IsReadOnly": false,
"MinLen": 1,
"DisplayValue": ""
},
"Property": {
"ColumnName": "UID_PersonNewManager",
"Type": 6,
"Display": "Neuer Manager",
"ValidReferencedTables": [
{
"TableName": "Person"
}
],
"FkRelation": {
"ParentTableName": "Person",
"ParentColumnName": "UID_Person"
}
}
},
{
"Value": {
"Value": true,
"IsReadOnly": false,
"MinLen": 0,
"DisplayValue": "Ja"
},
"Property": {
"ColumnName": "fe46ecd8-0251-0d9c-25e7-0257aad28dc3",
"Type": 0,
"Display": "GRP-test (Systemrolle)",
"Description": "Bestellung zum Stichtag abbestellen"
}
}
]
]
}
}

a second part is that on a Product unsubscribe no description is added in der Workflow and User as now Information why this Product was unsubscribed.

hope anybody can help

Best Regards
