amezianebelkessam,
Thanks for reaching out! I suspect that some styling in your theme is hiding labels, so you could try adding some CSS to fix this. Something like this:
#tribe-community-events label {
display:inline-block !important;
}
As you’ve confirmed that this is working correctly in the default theme, I unfortunately can’t provide any more support than this. Hopefully that gets you started in the right direction, but feel free to reach out to the developer of your theme if you have further questions.
Thanks! 🙂
