Items can't sync to remote device

I have four items on my Android that say they are out of sync. These items were unable to get updated, so I deleted them on this device. They are contained on my PC (host) but even if they are — and are deleted on the mobile device, they don’t disappear from failed items, nor do they get synced onto it.

I have set read/write on both but now realised the permissions on the phone changed to send only for some reason. This still leaves two remaining items. They are on PC, but can’t sync to the phone and they are as follows:

This usually happens when Syncthing is unable to write to the storage. What is your Android version? Is the folder located on internal or external storage? If it’s an SD card, then you need Android 11 or newer for Syncthing to be able to write data to it.

It’s Android 14 on LineageOS 21. It’s internal storage of the device. The conflicts seem to have disappeared now, and I’m not sure how and when that happened.
