Cannot create a new sheet from a template

Cannot create a new sheet from a template

I suddenly have a problem with templates. I cannot create a new page from a template. An example is:

Go to Wildflowers

Choose Templates

Click on Blank sub index

On file tab click on Save As

Type “Index B Latin"

 

Nothing happens, I cannot  create  a new page; what am I doing wrong?

Please help

Thanks and regards

Hans
