I've created an embed preset and set it as the default preset for all videos I upload on Vimeo. This preset removes everything but the play button. I have embedded the video that is the basis for the preset and it works correctly.
However, when I embed new videos uploaded with this preset as default, the CC button appears as well. This means that for these videos, the embedded player has the play button and CC button and nothing else.
Interestingly, I can't even manually remove the CC button for these videos under "https://vimeo.com/manage/videos/{video_id}/customize". All options are already turned off for that area, as I would expect because of the default preset, but the CC button is still there.
I am progammatically uploading these new videos using the Python client:
client.upload(file_name, data={
'name': title})
I have a Pro account. What am I missing?
