Clearing imagery cache doesn't work

[kallejre]

Ran into a problem where i created note 5153207 about missing footways only to discover that i had added those footways few days before. There's a button to clear imagery cache, but it doesn't seem to have any effect. Even clearing android's app cache at system level didn't help. App's debug logs show:
