tax calculation salary and dividends calculation on v22

using sage v22

salary £44,127

dividends £20,000

no other income

2018/19

the software calculates this incorrectly I believe as gives £34,500 at basic rate . £2000 at 0% and £15,777 @32.5%  -

should be £32,[email protected] 20%, £[email protected]% £[email protected]% and £17,[email protected]% shouldn't it?

this only appears to be wrong with this div and salary - I have checked others such as salary £32,127 and divs £38,000,  salary £24,127 and divs £40,000 and also salary £34,127 and divs £30,000 all of which are correct
