Email Timings - DST

We have an issue where the time is not correct when displaying within eM Client (v8.2.1237)

The time shows an hour ahead of our current time zone (BST) in the inbox but the actual time on the timestamp & header/source files are correct. The issue only began happening since our change with DST. The issue only happens with IMAP accounts not POP.

Any advice is appreciated but this may be a product bug as it displays fine in Outlook?
