Unable to delete attached file record

Thumb is well created but i get the ame issue on deleting attachment.
creating : directory is created in /files/attach and file is well uploaded.
View and download files from ProjeQtOr is ok.
Deleting file :
directory and files is deleting on server.
Error in log : [V11.1.5] 'stSaveRefType' is not an expected status in result <input type="hidden" id="lastSaveRefType" value="Project" /><input type="hidden" id="lastSaveRefId" value="386" />
386 is the id of project i use for test.

Reagrds,

Corrected with V11.2.2.
But i face an issue while upgrading.

My server can't reach Projeqtor.org for security reason (not only proxy).
So, i need to upload to server directly in installAuto/files.
Works fine, i get the entry to apply not version but, after decompressing, i get error message :
