Positioning PNGs

[Dallan]

Using V10.17

I have imported two identically sized png graphics and am trying to position one on top of another. I have applied Position effects to each with identical horizontal and vertical parameters, but they don't end up on top of one another. The vertical position for one png appears in the sequence preview incorrectly (aspect ratio is "match content"). But if I select for the vertical parameter "Show or hide animation line for this parameter" then suddenly the image snaps correctly into place. If I deselect this option the png moves back to its incorrect place.

Any ideas?

Can't replicate this in 10.17, when stacking two identical PNGs and applying the same positional effects to both.  Whether show/hide is enabled makes no difference.

Please upload both images and specify the effects settings.  Or upload the project.  Use a free server, get a shareable link, copy the link and post it here or in a private message.
