How to switch from Adobe Stock Credit Pack to 750 assets plan

Hello,

We have a subscription of 750 Adobe Stock images, and in addition to this, we sometimes purchase 150-credit packs for premium content. It seems that by default, we are using those credits even with the standard images that should be included in our monthly plan of 750 images, but we do not know how to see which option we are using (if monthly subscription or credit pack). Adobe stock website does not show nor ask which plan do I want to use. How can we standardize the usage of our 750 monthly images?

Thank you!
