Updated the windows aap to later version but still same issue. If i email you my login detail will it help you to fix the problem.
Can you please record the same video using the demo?
If you can reproduce the error there I should be able to as well.
Sorry for the trouble, I must be missing something…
see below video of your demo. same problem with product cost.
I see the issue, the app is behaving differently when selecting a product using the autocomplete vs clicking the + icon in the lower right corner. I’ve checked in a fix which will be included with the next release.
Thanks for your patience!
finally we found the problem 
. we will wait for next release. Thanks.
Still same problem in new version 5.8.2.
This should be corrected in the web app, the other apps haven’t been updated yet.
