TLS is just what some people type. It means the same thing as LTS. In the game it's always a "Limited Time Series" so then LTS. Been that way since update 4.3.

LTS and TLS are the same thing;
 * LTS = Limted Time Series
 * TLS = Time Limited Series

SE = Special Event. Completely different.

Here's a pic from 4.3
