I get that as well in the latest version of Chrome.
Even when the window is maximised and fills my large widescreen monitor.
I think the problem is that the width of the column is decided by the content, so any systems where there's no long names have a narrow column and a two-line title.
Systems (preview and active only) affected are: alakt, alba, bela, belb, belr, biha, canpe, cypa, finvt, finkt, glpn, hkgrt, hrva, imna, jamt, jeya, lkae, ltua, luxa, luxb, lvaa, mara, mexed, mtqa, mtqn, mytn, ncle, nclt, niram, reun, spmn, svna, svnh, tuna, twnf, usadc, usagu, usahi, usanes, wlft
