LibreOffice Calc v126.96.36.199 on Windows XP.
1. In Calc type in London in cell A1, Paris in cell A2.
2. Click in B1 cell and select Tools | Validity.
3. From default Criteria tab, from Allow drop-down box select Cell range.
4. Click in Source field and mark cells A1 to A2 and click OK button.
5. Click on "+" button at bottom next to Sheet1 tab to create a new sheet.
Problem: Drop-down validity arrow is displayed at B1 cell in NEW!!! sheet Sheet2.
Expected: Validity drop-down box should be sheet specific and should not appear in Sheet2.
Work-around: If I click on B1 cell and then to another cell like B2 then this drop-down box disappears.
