The WEB and desctop versions shows the different semtiment. Is it the bug?

Hi
The web  version of cTrader shows the different sentiment comparing to the descktop version.
How to replicate:
1. Run the web version
2, wait couple of hours
3. Compare the sentiment with the desktop version

The expected result:
The sentiment is the (approx) same 

The actual result:
The sentiment is different. The difference can not be explained by rounding of values.

If I refresh the web page with the charts (cTraderWeb) the sentiment becomes the same as on the cTraderDesktop
