Writer outline numbering incorrect

I am using outline numbering like this:

1 (Heading 1 paragraph style)

1.1 (Heading 2 paragraph style)





But with Heading3 paragraph style, showing 3 sub-levels, instead of 3.1.1 I have 1.1.1

I am having a lot of difficulty resolving this, if anyone can help?

LO version and OS? It would be easier if you could provide a sample file.

Edit your question through the edit link (with the slanted pencil); don"t use an answer).

Thanks for the advice, I had not used this forum before. I was using LibreOffice Version: On Linux Mint 17.2.
I had already tried Tools>Update All.
The issue resolved itself, once I closed the file and then re-opened it.
