lx-select error with lumx 1.0.5

[ciclick]

Hi,

I just updated from lumx 0.3.4 to 1.0.5 and now the lx-select elements created with angular formly shows all the object data in the selector list, not the choice option. I'm using angular-formly 8.2.1 and angular-formly-templates-lumx 2.0.5.

My objects:

vm.fields =[
{
"className": "row",
"fieldGroup": [
{
"className": "col-xs-10 col-sm-9",
"type": "lx-select",
"key": "media",
"templateOptions": {
'floating-label': false,
'placeholder': 'Mitjà del contacte',
'selected': 'name',
'choice': 'name',
'options': vm.medias,
'multiple': true,
'required': true
}
}
]
}
];

vm.options = [
{ name: 'Mitjà 1', idMedia: '1'},
{ name: 'Mitjà 2', idMedia: '2'}
];

And the select shows:
{"name":"Mitjà 1","idMedia":"1"}
{"name":"Mitjà 2","idMedia":"2"}

Instead of:
Mitjà 1
Mitjà 2

Seems that the template can't catch the "to.choice" variable

Thank you!
