@hassenmeier, I tried downloading dummy data (as CSV export) at my end and could see the hidden question. But let me also let you know that I followed the following steps:
- Had two dummy questions (one text question and one hidden question) and deployed the form.
- Made some dummy entries (approximately four submissions. Submitted the submissions to the server.
- Then, changed the text question to a hidden question and then the hidden question to a text question by downloading the form as XLSForm.
- Uploaded the form back to the sever. Redeployed the form.
- Then finally downloaded the data that is there in the server.
