Not Compatible With Multiple Subscriptions

Hello, I’m currently using Woocommerce Subscription Extension: https://woocommerce.com/products/woocommerce-subscriptions/

I noticed that when using Paypal Checkout, it removes and replace the subscription already in the cart when adding another subscription, is this supposed to happen?

To clarify, I made a subscription product that has multiple flavors. I want the customers to have the capability to subscribe to 2 different flavors, which I believe should be possible.

So like I said, when adding another subscription with a different flavor in the cart, it replace it instead of adding another item in the cart, and I get this message:

“A subscription has been removed from your cart. Due to payment gateway restrictions, different subscription products can not be purchased at the same time.”

I researched on why this message shows, and it seems to be payment gateway compatibility issues. But I checked the Payments section in Woocommerce and it states that it supports multiple subscriptions. See screenshot here: https://paste.pics/CDWGD

That being said, I tried disabling it, and use the built in Paypal payment gateway in Woocommerce. And using that I was able to add 2 different flavor subscriptions.

However, that is not the solution I need. I need Paypal Checkout since it can provide a Paypal button in the Cart page for normal products (that are not subscription products) which the built in Paypal could not.
