So far the only examples people sent are solved by using correct export settings or viewing the file correctly (yes, even such a simple task as viewing the file is a problem for people). Please show examples. Without them, it’s impossible for me to say if you are doing something wrong or if Figma has a bug (in this case your example would need to be sent to the Figma team so they can fix it, otherwise — no example, no way to reproduce the issue, no fix).
