A server failure this morning prevented the horse filter data from being uploaded.
I have now corrected this, but it is very likely that your copy of TheBetEngine has not been able to download this data.
This is not an issue if you do not use filters in your betting (gender or course/distance/course & distance/beaten favourite) but if you do rely on filters then you may need to force TheBetEngine to load the data.
Go to the Filters tab on one of your systems, and checked to see if "Not Loaded" is shown in red. If it is, then click on the "Not Loaded" text and TheBetEngine will attempt to load the data. If successful, the "Not Loaded" text will change to "Loaded" and will be shown in green.
Apologies for any inconvenience.
