Some applications are developed to run only on the Internal storage. That's why you don't see the option to move/transfer them to the SD card. To force this, the phone needs to be rooted and then you need to install an application called Link2SD. Use a blank class 10 ULTRA SD card and insert it, then start the application and follow its instructions.
There is also Adoptable Storage, but that's even more complicated so stick with Link2SD and you should be fine for app moving to SD Card.
