This bug was reported yesterday, and is now partially fixed. See: http://meta.stackexchange.com/questions/280023/excavator-and-marshal-badges-are-being-awarded-over-and-over and http://meta.stackexchange.com/questions/280040/extra-number-of-gold-badges-appearing-in-profile?lq=1.

The consensus from the moderaters seems to be that this should be fixed by tomorrow. For example, [Oded](http://meta.stackexchange.com/users/140505/oded) states ["This should get cleared up by a nightly job - lets see what it looks like tomorrow."](http://meta.stackexchange.com/questions/280040/extra-number-of-gold-badges-appearing-in-profile?lq=1#comment909107_280040)
