 ### DB/back-end
 
 ### UI not updating after DB change:
 BUG-3:		alter a condition, covertype, etc. and its not in drop-down list (even though db look via index is correct, e.g books.html shows updated covertype)
 BUG-7:		if you remove a series from a book, it won't appear in the series drop-down if it is the first 'missing' book in that series -- either reset the list, or show all series always?
+BUG-20:		broken gui with bs5:
+			* series add/rem needs to lose divs inside divs of input groups (and templ)
 
 ### ordering of data in UI:
 BUG-6:		author,series, etc. do not have explicit ordering like sub-books... sort of irritating / needs code and DB fix
