[HELP] how to set different sms app permanently? - Honor 6 b532

Hello, it seems that new lollipop build b532 keeps changing sms app back to default (huawei contacts) even if the new app (choms sms) is set as default in the default app menu in settings (tha app is additionally set to be 'trusted').
What's going on here??
Each time I leave my phone for a while, my default application is changed to huawei one:-/
Is there any way to set it once for all to 3rd party app?
