AI "File New" Interface size problem

When using Ai recently, I found that the legacy "File New" Interface is used to create a new document size with a decimal point of 2 /3 (such as 200.123*200.123mm) , and then create a new document size again, which will automatically bring out 4 decimal places (such as 200.1238*200.1238mm). Of course, I can delete decimals manually (such as 200 * 200mm). But there is still a problem that the size of the interface of the next new document will automatically bring out 4 digits after the decimal point (for example, 200.0003 * 200.0003mm).

I have tested three computers, and the same problem exists. This is not the case with the new file new interface. What is the problem, please? My computer system is macOS 10.14.6, Ai version is 24.1.
