Hi. I experience quite a lot, that lines occur crossing the different monitors. Crossing the words of each monitor when I’m at the watchlist page. I have tried to “reinstall” the monitors, and that helps for a short while, but then the lines reoccur. What do the mean? Thx.
@carolinepppsss does the text’s background turn light red if you hover your mouse over it? it is likely to a monitor’s preview text displayed in the watchlist. the preview text displays added text in bold and removed text using a strikethrough. here is an example:
unchanged text Added text and
deleted text
please note that deletions are displayed in the preview text only if there are no additions were found on the page.
let me know if you have any other questions.
Okay thx. The text does turn red. just to fully understand, if it goes red it doesn’t mean that anything is wrong? 
yes, it only indicates deleted content – there is no error.
