Description:
Hi everybody,

first of all thanks to all of you contributing to LibreOffice! It is a really great piece of software, even more if considered that it is available for free!

Now my problem: When I protect some cells/rows, including headers where autofilters are set only leaving all cells/rows below unprotected I cannot use the sorting provided by autofilters and get a message "Protected cells cannot be changed."

IMO this is strange since the headers which include the autofilfters won't be included into the sorting anyway.

So why can't I use the autofilter sorting while leaving according header cells protected (filtering works BTW)?

Thank you for some insights - would be great if this could be changed!

Bye

Steps to Reproduce:
1. Protect cells including headers with autofilters set but nothing below them
2. Enter some values within the rows below
3. Try sorting these values using the sort capability of autofilters

Actual Results:
Message occurs telling that protected cells cannot be changed.

Expected Results:
all lines below headers (with autofilters set) get sorted


Reproducible: Always
