Position Changes reset after unselecting a clip

Under Effect Controls, under Motion, when adjusting Position: With a clip selected, I double click on the y value, I adjust the y value by about 10 pixels by using the up/down arrow keys, I hit [enter] on my keyboard to confirm the change, I click on a different clip in the same timeline, I return to the prior clip where I adjusted the position, and the value has been reset to what it was before I made the change.

I demonstrate the issue twice in the attached video file.

There are no keyframes in any of the clips. I have the playback resolution set to ¼, paused resolution is set to full, and high quality playback is off. If I change the position by another means, such as dragging the clip around within the program monitor or manually typing in the entire y value, the issue does not seem to happen. Those methods are either too time consuming or do not allow me to make fine adjustments.

I have tried: restarting Premiere, restarting my computer, checking for software updates, checking for OS updates, clearing my media cache, et al. The issue still persists. I cannot find any documentation on this issue.

Computer Info: Macbook Pro Nov. 2024, Apple M4 Max Chip, 36GB Memory, MacOS 26.6.2 (25G83)

Software Info: Adobe Premiere Version 26.5.0 (Build 99)
