Autorouter version 8.11 routes some traces with wrong dimensions. This version of the Autorouter do finish autorouting, even if the track width does not fit the PADs for those components the track doesn't fit on to. In DRC rules you can define different track widths where each of those can be defined with different sizes of VIA's also. But the Autorouter do not respect the Via settings for the DRC it is routing. In the special track settings on the autorouter setup page, you can use only one setting for VIA dimensions. This causes problems, as the VIA settings should vary for different track vidths, but doesn't after auto routing,
