Well if they are booked through M&M as mentioned by me then they are reward seats / redemptions using miles. Unless you associate something else with M&M I meant to indicate Miles & More just to be clear.

Maybe the OP can shed some light as to where he / she is "looking/ monitoring" from? If Miles & More as a FFP program, I could book those 2022 Jan flights already 2 months ago as mileage redemptions though admittedly the other direction Europe - SE Asia, e.g. to SIN. I'm Blue M&M so nothing special.

If he / she is using another *A FFP then that could be a very different picture. For example on LifeMiles (Avianca) reward seats on LX may not show at all or only sporadically. YMMV.
