Image Erase returns "No Free Slots (9)"

[MB-Conti]

Hi,
I am experiencing problems with the nrf Device Manager App (v2.4.0). After performing a DFU I want to erase the old image in the secondary slot using the erase button.

Upon selecting "Erase" I receive the feedback "No Free Slots (9)". In the past I have not experienced this.

I am not to firm with app programming, however, in this repo I found that the erase functionality was worked on in the two past releases.

Any chance that this behaviour is a bug?

I have seen this as well, when I tried the image erase on an iPhone it was successful.

My guess is, that the secondary slot, which you want to erase, has pending flag set to true, that is Test or Confirm command was sent, but the device wasn't reset. Check it on Image Control pane in Image tab / Advanced view.

Or, I made a bug in the recent version of the library in #216. Could you paste logs from LogCat or nRF Logger app?

Hey, the pending flag are false.

My logs are below:
