Question

TheBat

After updating the Bat mail client from version 7.4.16 to 8.8, I got bugs instead of friendly names in the fields: "From:"; "TO:"; "And also to:", how to get back clear text? Before the update, on version 7.4.16, everything was fine.
The update was carried out as follows: they removed the old version, installed a new one, no more manipulations were performed.
