Hello again Pedro!
That certainly seems like odd behavior. Is this site running somewhere that I can see this happening? Feel free to respond in a private reply. 🙂
I noticed some oddities in the URLs for screenshots you shared. The first screenshots URL appears to be for month view, but as you stated and I witnessed, this is week view. In the second, the URL appears to be week view, but the view itself looks like photo view. I don’t think this is the key issue, but it does make me want to poke at the site a bit directly.
If this is not somewhere accessible, can you check if you have any JavaScript errors in your console?
In your other thread, I asked you to go through our guide for testing conflicts. If you go through that effort, it’d be worth taking a look at this during that testing as well.
