Broken /roles endpoint for accounts

[WeblinxIT]

Hey guys!

The /roles endpoint for accounts seems to be bugged. In my case most transactions are missing within this endpoint.
To make this problem visible first check https://api.helium.io/v1/accounts/13adMK1n7v3Z6SRmDsrVAbgEZSbCaoDMQUGSam2Ddkv4QUBrWCc/activity
there you will find every transaction for that wallet. After that check
https://api.helium.io/v1/accounts/13adMK1n7v3Z6SRmDsrVAbgEZSbCaoDMQUGSam2Ddkv4QUBrWCc/roles
There are only two transacitons visible (I waited for 24h now), all transactions after a specific point of time are not shown here.

EDIT: Maybe this is important: the wallet was created within the new Helium Wallet App.

Thanks for your help. If you need more information just contact me :-)
