Description:
Using Libreoffice 5.3.3.2 I attempted to open an additional sheet in Calc by 
Using Ubuntu 17.04 64bit and LibreOffie 5.3.3.2: Clicking on the "+" box in the lower left corner in a spreadsheet created in an earlier version of LibreOffice. Instead of opening a new sheet nothing happens. A spinbox can be opened with a right click but there is no "NEW" choice, only the ability to check an existing sheet.

Creating a new spreadsheet with 5.3.3.2 does not have this problem, and not all earlier created spreads have this problem.


Steps to Reproduce:
1. Open an older spreadsheet.
2. Insert a new sheet using a click on the "+" box in the lower left corner.
3. Perhaps nothing happens, perhaps it inserts a new sheet.

Actual Results:  
1. Open an older spreadsheet.
2. Insert a new sheet using a click on the "+" box in the lower left corner.
3. Perhaps nothing happens, perhaps it inserts a new sheet.

Expected Results:
With the particular problem spreadsheet, nothing happens. The desired outcome is the creation of a new sheet.


Reproducible: Always

User Profile Reset: No
