bugs in datafield post-install flow

A few days ago Garmin announced the new flow of datafield installation (https://forums.garmin.com/developer/connect-iq/b/news-announcements/posts/connect-iq-sdk-8-3-now-available)

fr965, FW: 25.04, CIQ 5.2.0, Connect IQ android: 2.40

After I install a datafield from the Connect IQ app, the watch indeed displays a new screen:

then I choose to install it to Walk activity:

BUG1: But then I was displayed this screen (which is not true):

However Walk activity has (and also had before I installed the new DF) only 1 datafield installed: Hiker DF

  

BUG2: And then when I scrolled through the Walk activity screens, the already installed CIQ field displayed a crash:

Note that the same happened when I tried to install to other activities that already had at least 1 CIQ datafield installed: it told me the max number was reached, and ALL the CIQ datafields were displaying the IQ icon.
