I created a bibliography using Zotero, it's set to APA 7th edition style, however there's inconsistency in structure. It's supposed to be "sentence case format" and it is at times and not others, here's a cut and paste from the first two references, both journal articles:

Beavers, K. M., Ambrosius, W. T., Rejeski, W. J., Burdette, J. H., Walkup, M. P., Sheedy, J. L., Nesbit, B. A., Gaukstern, J. E., Nicklas, B. J., & Marsh, A. P. (2017). Effect of Exercise Type During Intentional Weight Loss on Body Composition in Older Adults with Obesity. Obesity, 25(11), 1823–1829. https://doi.org/10.1002/oby.21977

Beavers, K. M., Beavers, D. P., Nesbit, B. A., Ambrosius, W. T., Marsh, A. P., Nicklas, B. J., & Rejeski, W. J. (2014). Effect of an 18-month physical activity and weight loss intervention on body composition in overweight and obese older adults: Exercise, Weight Loss and Body Composition. Obesity, 22(2), 325–331. https://doi.org/10.1002/oby.20607

You can see that the first reference does not follow sentence case format while the second does. Please let me know how to resolve this issue.

Thanks!
