Empty Paypal settings after update S2 Member Pro

I’ve updated from Version 150203 + s2Member Pro v150203 to Version 170722 + s2Member Pro v170722
with Pro manual ftp download after framework was updated.
I had sucess notification, but all the Paypal settings (Paypal Options and Pro-forms) are empty or reset to default.
S2 General Options are ok.

I would appreciate any help.

Thank you.
Phil
