Can't see full list of event logs

Today i've found an issue that when i set some time interval and apply it and then press on an events count number it only shows 7-10 and do not show scrollbar, even though there are 200-300 of events and it is set to show 100 per page. Same happening with Firefox and IE11. Maybe the latest browsers updates has changed something. Or maybe it is some sort of database corruption as the server hanged today (which has ELA installed, was 100% CPU usage). But it shows that there are 200 logs and i can flip through pages, but the view is for some reason limited to a few lines and there is no way to expand it.
