we are using Aspose Cells for Java (Version 19.10) and it seems that there is a problem with update of formula in excel files of type xls.
After calling calculateFormula() and saving to xls or pdf some formula fields are not resolved.
Doing the same with identical excel file that is based on xlsx the problem does not occure!
I think the underlying problem is that the given excel file has links to other files that do not exist anymore (see Excel Unknown Link.png in zip-file).
It seems that in case of xls these source files will be freshed in case of xlsx there is no refresh.
Obviously we would prefer the result of xlsx variant in xls variant too.
I have added a file to reproduce the problem.
