As per their Investor Presentation (Page 8), it appears, similar to Embassy REITs dividend, TDS of 7.5% was withheld on the interest component of that dividend (0.53 of the 4.78), hence the interest portion dividend got reduced to 0.49025 (0.53 - 0.53 * 0.075). And due to that, the total dividend per share got reduced to 4.74025 (4.25+0.49025).
Their website mentions about this TDS deduction -
No TDS shall be deducted on distribution in the form of dividend as none of the Special Purpose Vehicles of MREIT have opted for the beneficial tax regime under section 115BAA of the Act. However, TDS shall be deducted on distribution in the form of interest as per the provisions of section 194LBA of the Act.
