Description:
I have built several spreadsheets and set certain cells to be selected for input. Recently, when pressing enter or tab, cell focus has jumped to protected cells outside the format area. I have checked the formatting several times and have gone so far as to select all (except desired area), clear contents, delete entire columns and rows. The problem still remains, when entering data into the spreadsheets, using enter or tab goes "off sheet" to undesirable locations which is extremely annoying. This "problem started a few months ago (used to work fine). Hoped the recent upgrade would fix the issue, however it has not. I am using Libreoffice 6.4.2.2 in Windows 10. The problem persists on both my desktop and my laptop so it is not machine specific. Thanks in advance for any help or insight you may be able to provide.

Steps to Reproduce:
1.Create sheet and format desired cells as unprotected
2.Protect sheet
3.enter data into first first data cell press enter or tab

Actual Results:
After selecting the first unprotected cell in the first row, entering data and pressing "Enter" or "Tab", focus moves to next unprotected cell to the right for data entry if in the same row. If there are no more "unprotected cells in the current row, pressing "Enter" or "Tab" will jump to an "protected cell" outside the formatted sheet area. It will keep selecting cells to the right for several cells, then jump back into the formatted area at which time it will then stay within the formatted area until the document is closed and reopened. If I select the first cell in the top row and hold the "Enter" key until it runs through selecting "outside the formatted area" and returns to the unprotected cells, I can then begin entering data and jump to each cell in sequence as expected.
The issue reasserts itself every time the document is opened for data entry.

Expected Results:
select first cell for data entry, move to next unprotected cell to the right for data entry on "Enter". Continue to the right until last unprotected cell is entered, then move to the first unprotected cell in the next row for data entry. Continue until entering data in all cells across each row is complete, then return to first data cell in the top row when pressing "Enter".
