On top left panel in the HUD, the Calorie count field is too large once it reaches 4 figures (1000+) and overlaps with the "Cal" text. Either use a smaller font or shift the text around to create more space.
The ETA is usually shown in the second panel on the left but is not available when doing a recognised climb. The previous version showed ETA under the progress bar at the bottom of the screen. Consider restoring this.
Also in this panel, the AVG gradient remaining shoes + or - values until the total climb remaining equals zero, at which point it will no longer show a negative average gradient.
