Issue with Theme Blueprint Tabs

Sorry to double post (here and https://github.com/getgrav/grav-plugin-admin/issues/954 )

I just want to know if someone has the same issue as me with theme blueprint or if i’m doing something wrong.
When have more than 10 tabs in my theme blueprints, the first tab add fields from tab 11 and tab11 add fields from tab1 and so on with tabs greater than 10 014280bc-e962-11e6-874d-f665b30c7ab3

Thanks again
