UIpath Adding percentage automaticly

Hi all,
Why is Uipath adding “%” mark automaticaly?

Example:
In the “type into” activity
This is what I was expected:
“[k(enter)]”

but this is what I get after I type the “[k(enter)]” then click away:
“%[k(enter)]”

Regards,
Steven

@caoshixiao, You need not type it, You can select the enter command which is available
