Bitbucket Marketplace Filter not possible within all categories

Hi, 

I currently installed Bitbucket Server and having troubles accessing the marketplace. Bitbucket Server 5.7.0.

If I use a filter (featured, highest-rated, popular etc.) on "All Categories" (use of German "Alle Kategorien"), a warning appears in logfile:

"GET /rest/plugins/1.0/available/featured HTTP/1.0" c.a.upm.pac.AddonMarketplaceQueries Marketplace product query failed: com.atlassian.marketplace.client.MpacException$ServerError: 400: category: Allowable values are "Admin tools", "Blueprints", "Build management", "Charts & diagramming", "Continuous integration", "Custom fields", "Dashboard gadgets", "Design tools", "Document management", "Documentation", "Email", "IT & helpdesk", "Integrations", "Language packs", "Macros", "Messaging", "Mobile", "Monitoring", "Project management", "Reports", "Repository connectors", "Repository hooks", "Shared workflows", "Source code", "Tasks", "Testing & QA", "Themes & styles", "Time tracking", "Utilities", "Workflow"

After taking a look into the source code I found the bug: An i18n error. I have currently a Starter Licence, so I can not report the bug to Atlassian directly

<div class="fancy-select category">
