If the sample type name or UDFs are changed afterwards, these changes are not visible in the already existing samples.
For example the sample type "cell x" is changed in "cell xy", all the samples "cell x" are renamed as "cell xy" without any indication that the original name of the sample type was different.
Another example: if one UDF is deleted (UDF not assigned to the sample type anymore), this information disappears in the sample overview. After reassigning this UDF to the sample type, the information is back.
Suggestion: Can those changes be somehow labeled so that one is aware that a change was done? Removed UDFs might be displayed in grey to clarify that the UDF was removed and so that the information is not lost.
