List count not correct

[geocachermgo]

Describe the bug:
A cache is incorrectly shown a member of an empty list.

I had a cache stored in the list "ReiseLog" and removed it from that list.

Afterwards it was still shown as in this list, despite the list being empty. (Screenshot 1)
After click on the pencil button it showed Screenshot 2, confirming "ReiseLog" having 0 caches.

Actual behavior/state after performing these steps:

You forgot the screenshots.
I assume this could be a refresh problem after modifying the list.

[geocachermgo]

I added screenshots yesterday but it seems that it did not work.

[Lineflyer]

Thanks.
Can you provide a step-by-step instruction how to reproduce this (e.g. which function did you use to remove the cache from the list)?

[geocachermgo]

1. Create an list with one cache (in my example: "ReiseLog") and a list with some caches including (in my example "Germersheim") the one cache
2. Open Cache (Screenshot 1)
3. Click at one cache list "ReiseLog"
4. Menu, Caches verwalten, Alle verschieben, "Germersheim"
5. Report appears "List is empty, delete" ==> Abort
6. top left corner: back arrow
   Cache is shown again.
   Both lists are still mentioned. This is a bug
7. Tap on pencil (Screenshot 2)
   Empty list is marked with 0 elements but hook at empty list is set

Thanks.
I guess the "trigger point" is, that you accessed the lists from their link inside of a cache, where we miss to update the list information when coming back to cache details page.

[geocachermgo]

So is this a known bug?

[Lineflyer]

No, just my guess which need to be investigated by someone who is not just guessing. ;)

[Lineflyer]

Assigning myself for a retest using the given scenario above.

Checked it with 2021.12.21-NB-944fcba. Bug is still present.
