Restrictions on download traffic is bugged!

1. After I input my desired download speeds (Low: 32KB/s, Medium: 64KB/s),
I can still switch back to using Limit Bandwidth options, however once I restarted FDM, the settings stuck with the 32KB/s and 64KB/s and I had switch back to Limit Bandwidth manually. Only uninstall and reinstall is the solution. Please fix!

2. As advertised, desirable speeds often being ignored and exceeds well past the limit. This also includes the Limit Bandwidth by percentage option. Please fix!
