LN 8.5.2 doesn't sort emails by sender name

HiIt looks like after upgrading to Notes Client 8.5.2, when I click on the bar to sort on sender names the client doesn’t sort any more. Even funnier than that, if I click to sort by the next item in the bar it sorts by name. Anyone else experiencing the same issue ? What should I do to fix this issue ?

Thanks,

TGP

Subject: It is woking fine here

I have an 8.5.2 server, mail file with the 8.5.2 template and an 8.5.2 client. Clicking the subject bar causes the normal sorting to take place.
