does TG ever block standard fare class a certain amount of time out?

I'm looking at BKK=CNX 11Nov2024 - 15Nov2024 and strangely it seems all flights for these two dates have 0 tickets for the L V W S K T buckets, and it seems it's the case for flights +/- 3 as well (from EF). Surely these flights every day aren't so popular that there isn't a single standard fare available? lol

I'm new to booking with TG (first time) so would appreciate any insight.

If it's relevant I'm using google chrome - have tried via google flights and the actual TG website too but it returns the same result.
