Ashmanov Bifurcation

On the website of Ashmanov and Partners, one logo hangs in the plate at the top, and on the conference website eTarget is completely different.





Tell me, please, what is happening? Which logo is correct?
It seems that the correct one is on the site, but it seems that the correct one may be different, which on eTarget is fresh.

In general, this is not the case when such a mess with the company logo.
