ok i think the problem is that when you unchecked UL, made the changes and rechecked UL and press ok, it dnt really effect the settings because the deactivation of UL dnt really take effect
once again simple steps bro to get it working for you

1 go to settings/today, uncheck UL and check HTC home on your today (PRESS OK TO MAKE THE CHANGES EFFECTIVE)
2 check your today screen to see if you have HTC home active but not within UL (ok now you can change the settings)
3 go back to settings/today and in the HTC home section (not the today checklist, check the bottom and you will find a slab that says HTC home) and uncheck everything exept the weather tab and press ok
4 check your today screen and see if the changes you made took effect
5 if they did, then go back to settings/today and uncheck HTC home and once again check UL
6 those changes should have taken effect in the HTC home within UL
