Foreign (exotic) languages appearing in the section My Recent Modification

Hello,
today I updated our test install XWiki from 15.10.3 to 15.10.4. The server is Debian, server is Apache2 with Tomcat9 and Postgresql.

Following How to remove an entry in the navigation bar when related page does not exist? - #8 by jmarkoll and How to remove an entry in the navigation bar when related page does not exist? - #10 by vmassol

Now it is not Ukrainian anymore but Corean language.

샌드박스 테스트 페이지 1 according to Deepl.com is Corean and means Sandbox Test Page 1 (which is consistant with last pages visited, but not the language!)

As said in the former thread, only English is setup in this installation.

Hello,

Today the non latin characters entry in the right sidebar is still here.

After @vmassol had commented on this page How to remove an entry in the navigation bar when related page does not exist? - #10 by vmassol, related to strangely appearing foreign words in the right sidebar, I am coming again to report the same found foreign language as last time after I finished restarting XWiki post update : 샌드박스 테스트 페이지 1.
It still says in Corean : Sandbox Test Page 1
(in Debian VM with the latest 15.10.5 freshly updated XWiki edition).

Each time it occurs, only one entry is in a foreign language : either ukrainian, or in an asian language, or other non latin characters.
I have seen it occur several times along months of testings.

What should I make of it?
