ipod touch 4th generation ios 6.1.6 apps stuck

Two apps seem have become stuck in the 'install' mode, after I was prompted to update them...they are bbc iplayer and youtube, both apps I use a lot. I cannot delete them manually from my ipod because as they are greyed in 'install' mode the little 'x' in the corner doesn't appear. I tried deleting them in the apps section of the sync page of itunes, applied the change, re-backed up my ipod and then tried to restore it from the just saved backup...but its still not getting rid of the apps stuck in their install mode. Would I have to entirely restore the ipod to get out of this?
