[PLUG] Libre Office Calc merge and center cells broken

[Dick Steffens]

Is anyone else having trouble with merge and center cells in Libre 
Office Calc, Version: 6.4.7.2?

It's worked correctly for years, but recently quite working. On the 
toolbar there is an icon that used to cause the contents of a selected 
group of cells to merge and center. That icon is grayed out. There is an 
option in Format > Cells > Alignment, Text Alignment, Horizontal Center, 
Vertical, Middle. But the vertical option only allows "Default". This is 
not a critical issue, but it is annoying.
