@Talbs Thank you for the feedback and I am working hard to fix the issues you have mentioned. I hope you have updated the app and claimed your free booster pack to help people get going. The 2 resource amounts are Income and Current Resources. Cards cost resources to play and they also have an upkeep cost so when playing a card you need to have the correct resources to summon and to run that card. That is why you see both values go down because your spending resources (the big numbers) and also your Income is going down because you have to pay that cards upkeep.
We are getting updates out weekly to upgrade the things that get mentioned and with each update comes rewards for everyone.
Keep the feedback coming.
