[Koha] Acquisitions Language Questions

I have some questions about language used on the Acq page. When you're on the Fund page (/cgi-bin/koha/admin/aqbudgets.pl?budget_period_id=5) it says: Fund code Fund name Total allocated Base-level allocated Base-level spent Total sublevels spent Base-level remaining Actions but on /cgi-bin/koha/acqui/acqui-home.pl is says Fund Owner Branch Amount Ordered Spent Avail Shouldn't we use the same language on both pages? Also, what is the difference between base-level and total? They seem to have the same numbers in them for me. Nicole
