Problem Description

We have a Case Template with 16 custom fields.
Some of them are pre-populated with default values.
trying to add a default value to some of the existing fields (currently not populated) we can correctly perform such action, save it, the notification of the save action appears and it confirm that the save has been done.
Refreshing the page and opening again the case template, the previously addedd default values are no longer present. (This occurs editing a single field or more than one at time)
the problem is occurring only on boolean fields and only if the choosen value is = false.
choosing ''true'' the field is properly saved and visible while reopening the template.
while ''false'' value disappear.

Steps to Reproduce

step 1 Open an existing case template (in our case the problematic one has 16 custom fields)
step 2 add a default value for one or more boolean custom fields using ''false'' as value
step 3 save the template
step 4 reopen the case template and check if the populated value is still there

Possible Solutions

none
