1. What is the issue? Please be detailed.
From the docs
When using repeat_count, no repeat instances are deleted if the count is set to a value and then later decreased. This avoids accidental data loss: a user who accidentally sets the count too low will not lose the repeat instances they had previously filled out.
In Webforms v1.0.0 (and Enketo), lowering the value that is used for repeat_count will remove repeat instances and any data within.
While this is consistent with Enketo, it is not consistent with Collect or documentation.
