  In this work, I report that large fraction of stars detected by \'Ad\'am et
al. (2023, A&A, 674, A170, arXiv:2304.08394) and noted in that work as new
discoveries are in fact known systems. This is especially true for the dense
bulge fields with large blending of nearby sources. Among the published 245
stars determined to be doubly eclipsing (i.e. containing two eclipsing
signals), I identified 53 blends. In other words, about a quarter of the
systems noted by \'Ad\'am et al. (2023, A&A, 674, A170) are not actually doubly
eclipsing; rather, these are contaminations of known nearby sources that have
already been detected by OGLE. Such a high proportion of reported false
positives should not be readily ignored and ought to be addressed in future
studies.
