roblox.serializeModel not saving StyleSheet property in StyleLink instances

[devvf]

        <Properties>
          <string name="Name">StyleLink</string>
          <BinaryString name="AttributesSerialize"></BinaryString>
          <SecurityCapabilities name="Capabilities">0</SecurityCapabilities>
          <bool name="DefinesCapabilities">false</bool>
          <int64 name="SourceAssetId">-1</int64>
          <Ref name="StyleSheet">null</Ref>
          <BinaryString name="Tags"></BinaryString>
        </Properties>
      </Item>

After using the roblox.serializeModel function I get <Ref name="StyleSheet">null</Ref> despite having specified a style sheet in studio. This is frustrating as I have to manually reassign my stylesheets to my ScreenGui instances every time I boot up my workflow.

Here is what the StyleLink instance's properties look like in studio, and below is the StyleSheets which are perfectly serialized by lune as well.

Would love some clarity on this, cheers.
