Applying server hotfix doesn't change full Enforce and Detection servers version number.
When we apply a hotfix on the Enforce, the GUI (Servers-Overview) still shows 15.8 MP1 (15.8.00100.01075) instead 15.8.00105.01006.
This is by design. The current 15.8 MP1 or 15.8 MP2 hotfixes don't update the version number of DLP servers on enforce UI.
