after an update to 9.1.2, I have on some files yellow exclamation marks.
The files are not synced with the server, I checked with login by http.
Before updating from a 7.xx Owncloud, all files were synced perfektly (including the ones, that have the exclamation mark now).
What I have done: I have updated Owncloud form a old 7.x to the newest 9.1.2.
To have a clean update, I deleted all old owncloud files including config and data and the whole MySQL database.
Then I uploadet the new files and did the installation procedure.
So far, all worked well.
After syncing my personal data (pictures, documents, movies, etc.) with Windows desktop client 2.2.4 (build 6408) on Windows 10, some files have these yellow mark.
Some are .jpg, some are .pdf, some are others.
All the unsynced files have a red x
The logfile at the non synced files tell me, that some files are locked - but I never lock files (how can I do this?).
Here you can see the log file:

There are way more unsynced files, who are not listed in the log file in the client.
I don't know why.
Owncloud 9.1.2 is running on Apache with PHP 5.6 and MySQL 5.6.
Can you give me some advice, what can I do?
