Tags not saving in evernote desktop

[charlie72 1]

Tried to attach the tag *drawing sample* to an evernote note but it seems to be greyed out. Trival little issue until I go and try to find this note again in 6 months time. 

Generally, I'm finding lately, that any information I put into EN that I must check that it has saved the information. Pulling stuff off web clipper, emailing, uploading pics or docs it seems now to be standard to make sure that the info is there. This is far from an ideal productivity but a standard I've implemented given I've lost images that I thought where loaded into EN.
