label-variant not saved

[octavonu]

Hello,

I have added the label-variant property to a TextInput Control
as it shown in the example below.
In the flow preview I can see the property working correctly, but as soon as I press save, this property will be dropped.

I have tried to upload the same json Flow over the graph.facebook.com/v22.0 but the property it will be deleted on Meta side.

Thank you

BEFORE SAVE

"pattern": "^[0-9]?$",
"helper-text": "Cantitate maxima 9 ",
"input-type": "text",

Hello - unfortunately, we cannot reproduce this issue.
One possible explanation is that in a case of error on saving or uploading, the update to the JSON is not taking effect, giving the impression the param "label-variant" is dropped.
Did you see any error on saving in the builder or uploading via API?
