Search functionality broken in BambuHandy App

For me it seems like the Search function in BambuHandy app is somehow broken.

If I look for a specific model e.g. a refill spool for Bambulab refill filament and I enter „Refill Spool“ in the Makerworld website Search bar I get a valid search result containing mainly refill spools or accessories.

If I enter the same search term in the model search in the BambuHandy App, I get a result that has nothing to do with „Refill Spools“ but seems to contain a list of mixed results for the single terms „Refill“ and „Spool“ which makes the results nearly unusable.

Extremely, if I search for a specific model from which I know the name, it is nearly impossible to find this in the BambuHandy App. For example if I look for „Bambu Reusable Hex Spool with Label“ I get the right model as first search result on the Makerworld website.
In the BambuHandy App I am not able to find this model in the first 50 results that I checked.

Am I doing something wrong or is this behavior the same for you as well?
Is there any other way to find a specific model in BambuHandy?

Also trying to open the model via the „open in BambuHandy“ button does not work, as it only links to the Start page in BambuHandy…
