Dual Sim phone and answering on phone call by text message - problem (Fenix 5X Plus)

Hi

I have Huawei P20 Pro (I also tested in with Xiomi Redmi 4A). The phone is with Dual Sim. When I get text message on my phone and I choose "Answer" on the watch the phone is choosing right SIM card to do it (the answer is going out from the phone according to SIM card on which I get text). so, it is OK. But during incomming phone call the application is sending text always from SIM card 1 (do not take information from which CARD there is incomming phone call). It should send text via SIM card which is used to incoming call. 

Firmware version 7.10. Fenix 5X Plus

Regards,

Krzysztof
