We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
I have checked the form in your account and found some conditions there:
Conditions on your form can be deleted only if you edited the form, there is no a way that they get deleted without any action, you may check the history on your form and find changes made on it, you may also restore your form to a version where all conditions were there, here is the guide to do it: How-to-view-form-revision-history
If you still think there is an issue, please take some screenshots of the current conditions and then if you find that there are some missing, provide us a screenshot of both before and after the issue, we will be glad to further check your form.
If you have shared your login credentials with someone else then it may be a reason why you're seeing changes on your form, if you have shared it with a sub-user account or if you're a sub-user account then it could be a reason why you are seeing changes on your form.
Please let us know if we can assist you, we'll be glad to help.
