extra decimal places

Hello experts

from yesterday i found out that some computers have the following problem. by executing queries, most of the numbered fields such as quantity are displayed with decimal places such as quantity:60,000 and other fields such as sum appears more decimal places than before such as

(two days ago)totalsum:69.57

(today)totalsum:69.572123

i found out that this problem does not happen in all workstations.

for example, my computer has the following licence

SAP Business One 2005 A (6.80.318) SP: 01 PL: 12

two other computers with the problem have the following licence

SAP Business One 2005 A (6.80.318) SP: 01 PL: 10

we upgrades the PL from 10 to 12 but still the same problem with decimal places

do you have any opinion how to fix it?

i have checked as well under administration->initial setupappearance tab->decimal places

and these options are as mine
