In this post you already have a flow that works as expected, I think (??) or at least it does what it needs to do when you turn it on.
So why use the flow in Advanced Flow Working in Test State But Failing Once Saved - #21 by Ruckus
I think the ‘problem’ was that you do not want the dim-starting with 100% and then dim to 25%?
I do not know how fast the dimmer works on your light: what if you do a flow like (to test)
When turned on → dim 1% → maybe wait 1 sec → 25%
