Calendar card and Google calendar integrations - imported calendar problem

Hello Homies,
can anyone help me with new Calendar card and Google Calendar integration? I added my google calendar as instructed in docs, everything semeed to be ok, but there is one problem. I have one calendar added to my google account which is shared with me by someone else (its my company’s calendar of their events). And this particular calendar is displayed in Calendar card on a weird way. Some events are desplayed on a monthly view and some don’t. And for example if I click on date 10 Oct 2020, to see the daily view, it is still empty - no events there, but when I click arrow > (go to the next day), and than back again to 10 Oct, all planned events are visible.
When I check this calendar on my google account, everything is fine. Only HA displays it wrong. Does enyone have similar problem? What may cause it?

This is how october looks in my google cal

and this is how it is visible in my HA calendard card. Shows only few events 28th
