Softstart in V24.07 not working anymore..?working perfect with V25

[WP-Rue]

I'm still running my heat pump with V24.7- and I want to reactivate Softstart., because it is getting warmer outside :-) . It worked fine last year with Version 24.03, but now I have problems..The Outlet went up 6°C higher! Than I stop softstart manually. Is it a good idea to update to a newer version? Greeting Rue

I increase Phase 1 catch duration from default to 275sec. And Message delay from 3 to 4 sec. But the same result..
