Launcher background image not updating (Classic mode)

[Chakrabortysoura]

so the launcher otherwise is working fine for me but after the recent 2.5 patch update even though the game is running fine the launcher background is stuck with the previous background image of the previous 2.4 patch second phase. I checked in the launcher directory and it seems to have downloaded the new background but still it's not using this new 2.5 background image.
