Kantu select command doesn't work properly in combination with wrapping elements (metamorph.js)

Hello,

sorry for the unprecise title but I couldn’t describe it more ellaborate.
I’m currently struggling with targeting an option-tag within a select via the select-command.

The following HTML is my starting point:

All
		<script id="metamorph-167-start" type="text/x-placeholder"></script>
			<option id="ember2076" class="ember-view" value="warning">
				<script id="metamorph-170-start" type="text/x-placeholder"></script>
					Warning
				<script id="metamorph-170-end" type="text/x-placeholder"></script>
			</option>
		<script id="metamorph-167-end" type="text/x-placeholder"></script>
	<script id="metamorph-168-end" type="text/x-placeholder"></script>
<script id="metamorph-165-end" type="text/x-placeholder"></script>

Basically everything is wrapped in two metamroph script tags, one for start and one for end.

I tried to target the option with the label “Warning” as follows:

{
  "Command": "select",
  "Target": "css=.form-group:nth-of-type(6) .col-md-9 .row .col-md-3:nth-of-type(2)",
  "Value": "label=Warning"
}

the script part finds the appropriate select field when checking with the button “Find”, but doesn’T select the proper label/value.

Can someone help me out with this?
Can I also target the value-attributes of the option-tags?

Thanks in advance!
