Disabling Multiple Languages in Autocorrect

I use SwiftKey (the paid version) with English and my native language, Malayalam. My language settings are as in the screenshot below.

My phone is primarily for work use, so most of my keypad usage is to type out professional emails, Slack messages, Asana updates etc. and the only acceptable language for such communications is English. I use Malayalam occasionally on certain WhatsApp groups; where I know all members are capable of reading and understanding the language. In earlier versions of SwiftKey switching between these was quick and easy via the spacebar, and the product worked very well for my requirements.

But of late, I see that SwiftKey is predicting words in Malayalam when I'm typing in English and worse still, these words are offered as the middle prediction:

This is incredibly annoying; and I have searched all over the place - but it seems like there is no way to disable this behaviour. At the moment I have removed Malayalam from SwiftKey completely because this "feature" is interfering in my work. My questions:

1. Is it true that I cannot disable this feature?

2. Is there a way I can downgrade to a version of SwiftKey that did not have this feature?

3. Is there any plans for adding a configuration option to disable this feature? If yes when will that come out?

Thanks.
