Anonymous enumeration

[SigmaKlim]

Hi! I am using breathe and doxygen to generate documentation for a file which contains several anonymous enumerations.
The output page is fine, but the problem is that in output toctree I see this:

I would prefer to see just the enumerators as If they were constants. Or maybe something else, anything but not the 'PhonyNameDueToError'... Is there any way to achieve this?

UPD: I found my case in documentation, in which resulted documentation for this enum gets [anonymous] prefix, but I could not reproduce it. Please, help!
