Replaced MacBook Pro battery, getting erroneous low power boot screen

I recently replaced the battery in my MacBook Pro (Retina, 15-inch, Mid 2015) with a battery I purchased from iFixit. This computer model is also known by other names/idenfitiers, all of which are shown at the iFixit link below:

After installing the new battery, which went off without issue, I followed the recommended calibration procedures set out in the iFixit battery replacement guide. Now, the battery charges and discharges fine, and I'm satisfied with the lifespan of the new battery. However...
I've encountered a significant problem since replacing the battery. If I shut down the computer, or allow it to sleep by shutting the lid for a while, upon turning it back on I get a low power indication (see photo below):

I find the only remedy when this happens is to plug the computer into its AC adapter, at which point it'll turn on just fine. Every time I've done this, though, I discover the computer still has ample battery charge left when it turns on. I'm not talking 5 or 10%, it's always been 50%+.
I'm so confused as to why this is happening. Why will the computer run on battery power just fine, but needs a "jumpstart" from the AC adapter to get going?
I've tried resetting PRAM and SMC, and the issue has not resolved itself.
Any suggestions you may have are much appreciated. Thank you!
