While you wait for an answer please allow me to offer some advice, from Linux to Linux user: drop WINE. It's neither an emulator, nor even fully operational, and even their gold status for "supported" programs means nothing.
From experience (Linux/WINE/Heidi) and my own frustrating rides with my 80k title music library under Linux (not one music library under Linux is in any way usable for large, deep libraries) I know exactly how one feels when you can't find good software under Linux. My music problem was eventually solved by dual booting as to use MusicBee for windows; my mySQL/mariaDB/SQLite3 problems however nearly drove me insane. Not only thanks to WINE but also due to the numerous goblins in the background which constantly manipulated dependencies under Linux, resulting in some booboo or the other. As my fulltime job heavily relied on database operations my Linux systems soon required more maintenance than any of my former Windows systems ever required. I was simply not willing to risk my neck and job further by trusting useless junk like WINE.
Do yourself (and your data) a favor and get hold of a reliable, stable multi-platform programm that does not require some half-assed attempt of pseudo-interfacing Windows. I've been using DBeaver under Ubuntu (provided on-site as Debian- or RPM- download) for ages now and it never let me down, be it for my private DB data nor the humonguous multi-table jobs required for my work.
Without doubt Heidi is a fab job but it is made under (and for) Windows. Don't expect anybody to help with what in the end may (once again) turn out to be a WINE-related problem.
