Hi Nikolay,
I tried the 1.5.3 Beta, but seems still not solve the problem.
When i used the Beta version, the assets in Home Page shown negative values.
If we click the asset from Favorites menu, it will show this

- negative_assets.png (19.97 KiB) Viewed 14826 times
After that i tried to delete the assets and its solved the Grand Total calculation problem.
Maybe its related to some way of calculation on the assets.
I roll back to 1.5.1 and its fine, showing back the correct calculation of the Grand Total.
Temporary for the moment i will use the 1.5.1 version.
Thanks for the support. Hope my report could help.
Regards,
Bayu
