Actionsite version "reset"

Hi,

I had BES Server Actionsite Version: 5311.
Since last evening, it is reporting as BES Server Actionsite Version: 131.

If i run version of site “actionsite” in fixlet debugger on a client, the result is 5261.

What might be the cause of the “reset” is actionsite version for the server?

No upgrades on BigFix components were made.

Thank you!
