Please show the script. I have no idea what you are talking about.

Are #+ and #++ in the script itself or in its output?

It is the value of $PS4:

PS4    The value of this parameter is expanded as with PS1 and
       the value is printed before each command bash displays
       during an execution trace. The first character of PS4 is
       replicated multiple times, as necessary, to indicate
       multiple levels of indirection.  The default is ''+ ''.
