7.9.1. - bug column header log-windows (winbox)

After updating my routers (4011, wAP60ad-sa, wAP60ad, RB962UiGS, RDB53iG,…) from 7.9 to 7.9.1, via Winbox-V3.38 the column headings and the column division of the “LOG” window are no longer displayed correctly.

I have found the “detailed”-options. No Bug - in 7.9.1. Layer8-Issue
