Disappearing conditions problem

I am trying to add condition to the question to validate its input. However, I have experienced multiple instances where the condition that I put suddenly disappears when I either upload it on kobotoolbox, or I add the condition on the kobotoolbox website and still it disappears.

This becomes a challenge if I have to check everytime which condition is working and which isn’t. So waiting for your guidance. Thanks.

@apulikkal, if you have not, I would advise you to validate your XLSForm through this online validator. The online validator should be very helpful for you to identify syntax issues within your XLSForm.
