### Please describe the problem.
original issue: [https://github.com/datalad/datalad-fuse/issues/118](https://github.com/datalad/datalad-fuse/issues/118)
I obtained unexpected result from
```shell
(git)smaug:/mnt/btrfs/datasets/datalad/crawl/openneuro/ds000001[master]git
$> git annex whereis sub-02/anat/sub-02_inplaneT2.nii.gz
whereis sub-02/anat/sub-02_inplaneT2.nii.gz (2 copies)
8d2b6e96-ad81-44a5-99b4-0ec37d6b3800 -- s3-PUBLIC
b5dd2e3d-825f-4bc2-b719-cba1059f6bfc -- root@93184394ac19:/datalad/ds000001
ok
```
giving no URLs, whenever I expected it to be autoenabled
```
$> git annex info --autoenable
8d2b6e96-ad81-44a5-99b4-0ec37d6b3800 -- [s3-PUBLIC]
```
but overall `git annex info` not stating that it is enabled
```
$> git annex info | grep s3-PU
8d2b6e96-ad81-44a5-99b4-0ec37d6b3800 -- s3-PUBLIC
2.42 GB: 8d2b6e96-ad81-44a5-99b4-0ec37d6b3800 -- s3-PUBLIC
```
and looking to `.git/config` showed oddity -- it has different UUID!
```
$> grep -A2 s3-PUBLIC .git/config
[remote "s3-PUBLIC"]
annex-s3 = true
annex-uuid = deaa691f-c824-4416-9bf8-a94a47dd31b5
```
and then looking at remote.log we see the mess:
```
$> git show git-annex:remote.log | grep s3-PUBLIC

`git annex fsck` happily completes and nothing complains about nothing.
### What steps will reproduce the problem?
dunno... the history
repository is at http://github.com/OpenNeuroDatasets/ds000001 and it was in 30cf8f0cf99c9c98ab83ebca8d5c9708b563b2d4 Fri Aug 21 20:24:10 2020 +0000 when initial remote 8d2b6e96-ad81-44a5-99b4-0ec37d6b3800 was added . Actually by then there was already deaa691f-c824-4416-9bf8-a94a47dd31b5 but it was named differently -- `s3-PUBLIC-unversioned` . I just now spotted that it is there listed as well -- so multiple names for the same UUID. And multiple UUIDs for the same name... May be OpenNeuro folks could shine more light on this situation.
I would expect some warnings or even some fix by fsck in such a case.
To mitigate I `git remove s3-PUBLIC` and then `git annex enableremote s3-PUBLIC` and `whereis` started to work.
### What version of git-annex are you using? On what operating system?
ATM 10.20240430+git26-g5f61667f27-1~ndall+1 but I guess it is unrelated.
