When attempting to modify the notification settings in the SMSMSE console under Policies -> Exceptions, changes deploy successfully, but settings immediately revert to default when the console view refreshes.

The issue does not generate any visible errors within the user interface or within logs. Deploying Changes results in a "Success" message.

An API used in the submission process for notification changes is not correctly modifying registry values within the product.

 This issue is fixed in SMSMSE 7.5.1. Upgrade to 7.5.1 to resolve this issue.
