Activity Package Upgrades automatically

Scenario: In my UiPath Studio, the activity package gets auto updated even though the ‘auto update’ checkbox is turned off in the Manage package window. This sometimes makes the workflow break since the logic was compatible with a lower version on activity package. Very surprising to see this getting auto updated without user input. This behavior is seen in several machines in my project. Could you please let me know if there is workaround to prevent the auto upgrade of packages.
