Continuous renaming filename with numbers

Hello all,

I have filename with numbers started with 1 to 2 digits and 3 digits

[Test][1] mp4 > Test1 mp4
[Test]]20] mp4 > Test20 mp4
]Test][100] mp4 > Test100 mp4

I have been using it for multiple times. Now updated my version to 4.19 and it unable to rename above anymore.

How to continue rename filename numbers when I have numbers previously?

[Test][1]-[160 mp4] > Test1-160 mp4.
