2x2 Commercial plots not working

[Imemine]

My 2x2 commercial plots are no longer working. The plot can be placed and a settler assigned, but no building plans can be selected (* Random only). When I assign settlers to the plot, they never start the construction phase. All other plot types are not affected, including interior commercial plots.
Neither refreshing the plot, rebuilding or resetting the building plan solved the issue. Any ideas or suggestions on how to fix this?

The infamous random bug strikes again. So far there is no solution other than start over.
