The template palette of the BioviaDraw editor features both cyclopentane as regular shaped pentagon cyclopentane  as well as one derived by truncation of a hexagon, cyclopentane2.  While building a structure with cyclohexane and benzene on one hand, and cyclopentane2  on the other, I notice the sides of the two bonds enclosing an angle of 120 degrees of the later still match the side lengths of the two former.  Contrasting to the regular cyclopentane (first row of the screen photo below) and contrasting to expectation, the two "next" bonds in cyclopentane2 however do not (second row, example to the right hand side):

Though the regular shape is more frequently used, on occasion, the truncated shape (after a unilateral drag to about 104%) suits my needs better and I would welcome if future releases of the editior could ship with a template accordingly.  This discrepancy in side lengths equally is observed if i) the structures are marked, and subsequently redrawn e.g., by Load settings -> ACS document.  Or ii) the ACS1996 style is load ahead of using the templates.

Going back to an elder computer, this discrepancy equally can be observed e.g., with Biovia Draw 2017 R2, suggesting this "thing" is present for long.  On the other hand, it was not a problem in ISIS Draw 2.4, an ancestor to the present editor, found on an even older computer:

nor to other contemporary editors (provided if a truncated pentagram is available) such as Marvin:
