Regression for BOLD:ADC2696

More a question than a bug: in most other cases with BOLD mappings for order=Diptera, I see the previously applied taxon match switch to a BOLD id match - not so in this case though, where a previous BOLD match now switches to taxon match for the accepted name. I cannot identify what makes this case different from all the other ones(?)
