I am using the current version of MX Linux with the xfce desktop. I have happily used synaptic on various distros for years. However, I am unable to easily discern what the icons mean in the status column on your display. They are small, all are orange with only a small difference to indicate the status changes, which to my 64 year old eyes, is difficult to see. If you wish to use Icons, how about using a combination that offers more contrast? Larger icons would help too. Someone also suggested that the issue is from switching from gtk2 to gtk3. I wouldn't know but I do find the situation frustrating and would appreciate a solution soon.
