You're still a beginner so you'll only start to see real improvements much further down the line. I wouldn't worry about, just keep playing whatever time setting you feel most comfortable with.
Why am I good at Blitz but terrible at Standard

thanks for calling me a beginner. 1750 on Blitz is beginner level?! I've played over 6000 games on chess.com guess I just just be dumb😂

There is a reason that chess.com has different ratings for different styles of chess.
I know several people who are 1850 in bullet, but are no better than 1100 in rapid. Simply stated different time control makes an entirely different game, you will never be a good bullet player if you play rapid all day and you will never be a good rapid player if you play bullet all day long. 15/10 gives a lot more time per move, you are used to spending shorter amount of time's on your move, so the extra 10-15 seconds you get by playing the longer time control per move you just don't use.
Hope this was helpful.

Several people 1850 bullet with 1100 rating?
Show me your proof.
This survey shows 1850 bullet here has average rating 1800+ in any time control including FIDE OTB.

no kidding. I'll be winning against these 1400-1500 players. On Blitz I'd drive home the advantage, and the clock would force them into further errors. but this 15/10, they spend 4 minutes thinking up a cunning move (or cheating) and by that time I've got Facebook messages to read.

I too have played around 6000 games, not sure what point you're trying to make, but yes at 1700 I'd place you between beginner and intermediate.

Do you understand survey?
Did you learn statistics at school?

This is the general way of describing players based on rating. Beginner is around 1200. chess,com ratings start at 1200 for any new player. Below 1200 is usually a child player. 1700+ is "weak advanced level". Above stronger expert are various levels of Master.
Of course, chess.com ratings are probably 100 points lower than official ratings, but still, 1700 is not "beginner" in anyone's opinion!
