Sometimes you can see that the factbox is not displayed correctly in the web client although correctly in RTC Client. As you can see in the example in the attached picture there is the Group named <Control1121795000>. If you leave the default caption <Control1121795000> the layout of factbox will be disordered (see the attached picture).
To solve this issue is necessary to set own caption. I think one of the best solution is to insert single non visible char " " (by pressing Alt+160). Or select this char in CharMap app and use copy and paste.
