The fact you only see it with a bright object suggests it is a reflection of some sort. When the moon makes it's reappearance, try on that and see if you get a similar effect.

I'm using a 10" F4.7 and no there are no sources of light in the immediate vicinity. We usually turn all the house lights off so it's quite dark. I mean there are other houses around but the closest is approximately 60-80 metres away and even then the sheds block out most of the house.
Will give them a go next time the moon is up, but I've used both on the moon before and I don't remember noticing anything like this. Thanks for the suggestion.

Thanks for the suggestion Iain. Will keep that in mind next time we're out under the stars. Haven't had any issues with eye lashes getting caught up in any of our shorter FL eyepieces with shorter ER though. Not sure why that would affect only those particular eyepieces if that was the case. Crazier things have happened though.
I suppose one positive is that it affects both the 26 and 31 from what we've seen so at least I know it can't be anything wrong with the eyepieces. Unless both have something wrong haha
