The screenshot looks correct. You have 2 plans in the basket. They are as follows based off your description.
Plan 1
Initial Price: $23
Recurring Price: $69
Plan 2
Regular Price: $150
This means the first purchase of both plans would be $23 + $150. That would total $173 as shown in your screenshot. The recurring price would then be $69.
When you combine recurring and non-recurring the math can get strange. It'll try and calculate overage's and underage's relative to the recurring price. So in this case it has done the following $173 - $69 = $104 to get the difference between the two.
This however was implemented when Stripe's ability to add one time line items to recurring payments was very limited so that behavior can probably be improved in a future release. Regardless it will always total up to the correct amount. I've added a feature ticket for a future release since it should be doable now since recurring payments can have as many one time line items as needed now as previously only a single on time line item was supported by their API so this math behavior was necessary.
