What am I missing about max HP calculation for PCs (D&D 5e)

Hello, I'm a DM setting up a game for people new to the hobby.  I already DM a game for "oldtimers" and they all had their own characters and they manage own characters. Great. For the newbies, I went and created their characters, and everything looks good except Maximum HP does not match what I am seeing on my paper sheets.  So either I've been doing it wrong the whole time, or my guess is I have some checkbox turned off I should have turned on.  I used the charactermancer so I'm guessing it's this latter one.  None of them have feats that directly modify HP. The characters in question: Hill Dwarf Cleric level 7 with CON+3.   What I think it should be: 8+3+1+(6*(5+3+1))=66.  What the R20 sheet shows: 61.  In gear icon I can see HP Modifiers is set to Total Level Dwarven Toughness mod 1. Dragonborn Fighter level 7 with CON+3.  What I think it should be: 10+3+(6*(6+3))=67. What the R20 sheet shows: 54. Mountain Dwarf Ranger level 7 with CON+3. What I think it should be: 10+3+(6*(6+3))=67. What the R20 sheet shows: 54. Half Elf Bard level 7 with CON+1. What I think it should be: 8+1+(6*(5+1)) = 45. What the R20 sheet shows: 45!  Ok, well that ones is correct, so how'd I mess up the other ones??? Thanks in advance.

The sheet itself doesn't actually do any HP calculation at all - the charactermancer calculates the HP to add each level-up and adds it to whatever is currently in the @{hp} attribute. Since no record is kept of the HP additions, and rolling for HP is a possibility, there's no way for the sheet to calculate total HP each level up - it just assumes the current max HP value is correct and increases it by the current level-up amount. Example - make a level 1 ranger with 10 CON. You'll have 10HP. Now bump CON to 20 and use the charactermancer to level up to 2 with average HP - you'll now have 21HP, whereas it should be 26 due to CON mod changes applying hp retroactively. TLDR: just use your calculations, as the charactermancer is a bit clunky when it comes to multiple level ups at once, and will always get things wrong if there's a CON mod increase after level 1.

Ahhh, ok, thank you!
