"Profit & Loss" is a common name for a financial report that one might develop in Management Reporter. Our reports commonly abbreviate this as "P & L". In Management Report's left pane, the "P & L" report is being shown as " P _L". It appears that Management Reporter is processing the left pane items as if they are menu items and the ampersands are being converted to underlines.
This is not what the users desire as they'd like their "P & L" reports to display "P & L". Elsewhere in the program, the string displays correctly.
I opened a support request for this and was informed that it is a known issue, bug 351774. However, I don't think there is a public KB for it.
