BNG map filter doesn't accept coordinate with leading zeros

[SDScandrettKint]

If an X or Y coordinate begins or ends with a zero, the search won't accept the number due to the error "X and Y must both be 6 digit coordinates", as shown below. The 0 cannot be removed, as then it doesn't meet the 6 number criteria.

Oddly, if the grid reference that is created from one of these coordinates with a leading 0 is used, the search is successful but the same error of "X and Y must both be 6 digit coordinates" is displayed. Example:

AfHER_grid_reference_video.mp4

This means if you want to search a BNG that includes a leading 0, the grid reference must be used.
