This must be related to config as I've done a hard-reset and the problem has gone.

[2x-y]

Temporary fix, edit the "dimensions_and_batch_together" line in your config.json file so the value is true:

"dimensions_and_batch_together": true,

[BlackWyvern]

Cannot confirm. Config.json is not being changed/properly read from the settings panel on a 100% stock install. Even changing the option manually in editor, changing any other value immediately reverts to the default invalid state.

Edit: Did a full reinstall again. The only option I changed was to the show width/height in line option. And then saved. Settings said 7 options were changed, and the UI option was not applied. Immediately returns to invalid state.

Having same issue and can confirm setting "dimensions_and_batch_together": true, works as a workaround. I don't know the code but suspect this relates to the recent update that added a button for switching height/width.

[BlackWyvern]

It seems to be the case. As long as I do not change the width/height inline option, the settings appear to work.
