Plex question - listing files?

[ajf]

I have some TV episodes in Plex.
I labelled them Ep1, Ep2 etc etc.
When browsing them though, it shows them as Ep1, Ep10,Ep11, Ep2,Ep21 etc

Anyway to get it to list proper numeric?
I understand what it has done but it isn't what I want!

Only just started using Plex so perhaps just something I have missed?

Thanks for the comments all.
I'll have another look tonight at the suggestions and see which is the easiest option for me.

Tried The Renamer and it didn't seem to be able to find the episodes, so I tried filebot which mostly worked OK.
However, despite them named correctly now, Plex thinks they are something else!
They are episodes of NCIS, but Plex thinks they are Pokemon. lol

More work needed...
