Solidworks PDM notification error

Hi everyone! After updating from 2019 PDM to 2020SP3 something has broken. I mean when I receive the message about file statement changes sometimes I receive an ordinary email but sometimes I get this in the body:

SOLIDWORKS PDM r Int)

or 

SOLIDWORKS PDM ke 'Elec (in this case 'Elec it seems like not full file name)

So what's a solution to this kind of problem?
