sometimes Sync does not work after renaming page with move plugin

[Xeenych]

I have a local wiki on my laptop and remote one online both with page import:pageA. This page have some lnks to other pages in the same namespace
[[pageB]]
[[pageC]]
pageB and pageC have backlinks to pageA in a plain form [[pageA]]

I make changes in a local wiki and sync them to remote.
I use Move plugin to change namespace import:pageA -> pass:pageA
It works succesfully and replaces backlinks in pageB and pageC to a correct form [[pass:pageA]]

Then I try to sync changes in local wiki to remote. I use sync plugin on a local wiki.

The plugin shows all changed pages: pageA, pageB, pageC. I choose to keep local revision of all pages.

Then sync plugin shows progress and says it succesfully changed all the pages. But in fact it is not. Remote pages are not changed.
If I run sync again it shows all these pages again. It shows the size of the local and remote pages is the same. But the content is not.
I try to sync. It reports success, but changes are not made. Again and again.
