template wont save correct time period

hi, appreciate if someone can help, i have saved a daily chart template 6 months and made it my default and then added to the toolbar at base of chart it works fine.........i now want to add a weekly template chart of 5 years, after i set up chart and save this under file save template,  i then go to the customise template icon at base of chart and add the saved weekly 5 year template, all seems to go fine,  when i click on the  toolbar abbreviation for my new 5 year weekly candle chart it opens,  but the time frame is 3 years, i have repeated many times saved as 5 years but it reverts to 3 years?  ....i'm using bhp so there is plenty of data, ...i just want to have these shortcuts on the toolbar at base of chart so i can switch between 6 month day to 5 year week to 10 year month ect....help please....fiesta62

thanks robert, i have already done what you suggested to do a global timeframe that works across all templates, but its not perfect, does the job, but i would really like to set the number of bars different for day then week then month templates ect.....so hope someone at bull charts sorts it....thanks again...fiesta62
